1996-2017 Mustang SCT SF4/X4 Power Flash Tuner Review & Dyno

[@MTLbigJ]

I just want to give a little advice to my fellow mustang owners. This tuner will wake up your car, on my 2010 4.0 v6 it made a world of difference. However. Be careful to not overdo your tune adjustments. I brought my car to the strip, ran a 15.75, then I adjusted the transmission (auto) to shift later and I also increased my rev limit. It then ran a 15.65, but on my way home I started noticing a rattle. my cats had gotten way too hot because the engine revved too high. Moral of the story...Ford engines are built tough and WILL withstand these tunes...but keep in mind everything around your engine might not. Not looking for comments like "you're an idiot for over revving the car" I know my cats failing was completely my fault. All I'm trying to say is any time u tune ur car u reduce reliability. So just be careful

[@lilchristlike599]

What settings should I run it at I have a 2010 v6 mustang

[@Forgotten_performance]

The cats are unlikely directly caused by the shift points increasing, however it is a great opportunity to upgrade your exhaust system for a better flowing one

[@FerRod2113]

I’m not gonna lie, I bought a used unmarried SCT X4 tuner and I don’t have any tunes, so I used the little tune it comes with the device. Boy let me tell you, I wasn’t really expecting much besides being able to use my JLT intake finally but it woke my car up big time! I’m blown away, I wasn’t expecting much but it did make a nice noticeable difference for sure! Maybe not like the other tunes on the market but a huge improve from factory

[@2InfinityRKX]

U know where to get a custom tune? I just bought one too and notice the preloaded 91 octane tune really made a difference as far as drivability.

[@josephcanales4103]

So you can tune your jlt intake with it?

[@ygk5238]

@@2InfinityRKXgo to automafia some of the best tuning on the 5.0

[@everythingautomotiveeta5839]

Bought this for my 2014 GT and it being Sunday bama hasn't gotten back to me with my tunes. Out of sheer boredom I tuned my 5.0 with the canned 91 octane tune. Didn't expect anything. To my utter disbelief the car runs way better. Feels totally alive and woken up below the curve much more punchy for daily driving. Also feels like it pulls harder up top. The transmission shifts hard as hell now easily breaking traction on the 1 to 2 and even 2 to 3 shift. And the one that really surprised me the most was the sound. I can't explain it. But the car sounds a little more idk mean agressive throaty something along them lines. If bama is better than this, good lord.

[@Brickington23]

I use this bad boy for a gauge instead of actual aftermarket gauges when I drift my mustang so that and all the other features it offers made it worth every penny

[@proudamerican9306]

Just got my 6.4 powerstoke back today after a complete emissions delete intake swap and straight 4inch stainless exhaust got one of these tuners with it and tryed the race tune unbelievable crazy torque then its started raining I pretty much had to let it pull itself at idle until I switch tunes

[@J0hnnyBlueJay]

If you buy this tuner from American muscle be aware the sct4 they send you WILL NOT have Wi-Fi capability and WILL NOT have a header preloaded tune.

[@J0hnnyBlueJay]

They have this video on their website making it seem like it comes with the same features as in this video but it does not. Beware

[@toxicsss9613]

So we're would you get yours from

[@JesseAndMike]

Nice! Good results!

[@SaleenDrift]

Before choosing whether to go with SCT or HP, check in your area for custom tuners! You may NOT have anyone that would tune using SCT.

[@joemulbah5540]

Quick question, can you adjust the octane rating from 87 to 93 on the preloaded tune?

[@Hop]

I think you can.

[@calebdurham7710]

Yes

[@johnathanheatherman6438]

If youre on a V6 ford already has a base 93 tune on it. It and the ecoboost dyno the exact same on 93

[@gregory9740]

How do you get 10hp gain when the stock was 403 and tune was 405?

[@LiilTyweezy]

That's what I'm saying like she was saying some different from what she was showing to us

[@magictoaster806]

At around 4K rpm it was plus 10 hp

[@xAndyGRT336x]

gregory9740 curve gain is 10 hp peak is 2hp, picked up more power at mid range

[@crownvictoria7787]

2 hp not even worh it

[@wolfgangouille]

Yeah the difference is not statistically significant.

[@danielhaynes1642]

Wish I could pick other vehicles. That way my 5.4L swapped 96 mustang couple just pick the car it came from

[@thepigeongod3671]

Quick question I live in Utah I was wondering if I can run 91 on the 87?

[@jeremiahsimental6845]

Bought one for my 2013 mustang GT and kept getting a “unsupported vehicle” so never got to tune my car with it. Got it from summit racing came with no pre-loaded tunes

[@IQSean]

So I honestly know not much about this process. I'm looking to buy an 2001 Mustang GT mostly stock. If I get this device and hook it up. Would it work? Could I do it on my own? thank you

[@taylorasmer3390]

How do I get my device to get unmarried. It’s connected to my old mustang but I have a new one and I can’t use it. What do I have to do to get it unmarried?

[@ericengelberg143]

Taylor Asmer you have to send it to SCT to get it unmarried...

[@91sr20det]

You need to plug it to your old mustang and click return to stock then it will be unmarried when completed. If you don't have the car anymore then you have to sent it to sct to unlock it .

[@AltheRad]

Correct

[@Carllucas197]

Would a MPT tune be better than sct preloaded tune that comes with the device

[@jefrey5578]

Are you able to delete emissions parts?

[@americanmuscle]

No. -Justin

[@jonadesa8826]

This tune work for a v6 Mustang 3.7? I just want to delete the speed limit

[@jorgevillagomez3211]

Should I unplug my sct after I’m done loading tunes or can I leave it plugged in? I don’t want my battery to drain.

[@ansonantony5699]

It can use V6 manual mustang

[@Tom-m4u8e]

Would this work to tune the Roush Phase 1? I'm from the UK and Roush doesn't programme the ECU. Looking to get a decent tune then take for a Dyno.

[@parkerrollins774]

I’ve recently added the ford performance cold air intake and slp loudmouth on my 2006 v6 mustang and now it has the engine light on which is expected but it also idles weird when you start it and won’t let you gas it 100% idk what tune to get other than that it’s fine

[@Hauntedwolf88]

The ford performance intake requires a custom tune. You're running too lean (too much air not enough fuel) right now. The custom tune will balance that back out

[@parkerrollins774]

Hauntedwolf_88 Thanks I figured it out the second day I had it on had to put my stock one back on but about to get the tune

[@di-doubleTv]

Could you use this device for crown vics?

[@olafvikingwarrior2349]

Yes

[@riosangel7776]

Does this work on the 2021 gt?

[@arroyoalbert19]

Is there an option to add my super charger from the control settings? Or would I have to go to a tuner for this

[@madmod]

You would have to flash a new tune compensating for boost.

[@jonathanjuarez3797]

So my tire pressure sensors went out.. how can I fix this or what do I do?

[@americanmuscle]

You would have to replace the sensor in the valve stem, unfortunately a tuner won't help you with that. -Justin

[@magyverboles7947]

With this do you have to leave it plugged in at all times?

[@swervinjdizzle]

No

[@Eslamizar]

I wish there was a ford racing tune for my 3.7, that way I wouldn't have to worry about losing my warranty.

[@Knards]

You dont lose your warranty if you put a tune on. The only time you lose thew warranty is if something goes wrong and the dealer can put the blame on the tune itself. If you have a tune on, and the air conditioning goes bad, its still under warrenty

[@Hoffyone23]

MrMrwilson11 Hmmm. if something goes wrong inside the engine you don’t think ford will say it was because of the after market tune?

[@Knards]

It would have to be directly related to the tune. You can go to the district manager for arbitration. A tune does not void the warranty by itself. For instance, spun rod bearings really dont have anything to do with a tune.

[@robertcaballero8095]

You can easily take the tune off and put it back on

[@joeytm____133]

Would this work on a 2000 mustang v6 base model??

[@ryersonbyford9620]

It works on my 2001

[@woodburn2597]

Dose it work with crown Vic?

[@olafvikingwarrior2349]

Yes

[@s550joe3]

Can you disable the rear o2 sensors with this??

[@americanmuscle]

You cannot Joe- sorry. -Justin

[@lolley1100]

I don’t know about the S550, it doesn’t show it on the options when she tunes it on the vehicle in the video, but I have the same tuner and a 2013 Mustang and it definitely lets me turn off the rear O2’s out the box!

[@edryan562]

...Mustang.com, you borrowed my engine, but that's OK. (98 Lincoln Mark 8 LSC} now bark to loading my tune's...

[@3.7xavier83]

Do you have to keep it plugged in after you tune your car

[@JohnDoe-qq8et]

No

[@thr65]

Wast of money if your looking to only use it with the can tune....10hp for 500$$.....🤦🤦

[@jonasbaine3538]

Is this still the best tuner for a 15 mustang gt that is stock? Looking for first tuner to get for basic hp increase. Like 20+hp or more

[@uravggamer4620]

I would consider a Cobb Accessport. The performance gains seem to be a lot more prominent than with this tuner.

[@mrswaychocolate7492]

@@uravggamer4620 that’s for an ecoboost not a 5.0

[@uravggamer4620]

@@mrswaychocolate7492 I’m aware, but tunes are also available for these tuners that are compatible with 5.0’s. I have an ecoboost and ended up purchasing the BDX tuner and I couldn’t be happier with it.

[@hanijabry2360]

Its the same one

[@jasim9870]

Bama and SCT are they the same

[@StillNoPickles69]

Yes but bama comes with free tunes for life

[@jasonb.3874]

Show us the 93 octane results

[@Jay84]

15 HP to the wheels, about 25 HP to the crank for stock applications. With mods--it really depends, CAI, aftermarket exhaust/muffler, upgraded plugs/coils pack/wires, throttle bodies, etc.--you could see 25 to up to 100 crank ponies. I'm serious. Lmao.

do you have to keep this in at all times for it work? and if i set it to 87 octane but put 89 or 91 is that okay?

[@Djuane]

BlackJack21 you dont have to keep it in at all once the tune is loaded to the the vehicle. if you set it to 87 octane thats what the tune is adjusted for, you can run 89 or 91 but if the tune is 87 you just wont see any power gains unless you set it on the tuner.

[@joemulbah5540]

@@Djuane I was gonna ask that same question tho, mine is arriving today. I run 91 oct on my 2012 mustang. My question is, can I adjust the octane rating of the preloaded tune?

@@Djuane thanks for the quick reply bro! Last question, I planned on getting the mpt tune but it will be here at a later date. In the mean time I will like to try out the preloaded tune, do I have to go back to stock tune before downloading the mpt 91 prx tune?
