B58 Custom vs Off The Shelf Tunes Dyno Tested. What Is The Difference? MK5 Supra MHD Tuning

[@derianc3]

I’ve been on an ots e40 map and this video convinced me to go custom tune, currently waiting for my file to be created

[@ghetto-lemon]

does mhd have a e40 ots-map?

[@bmwcodesnyc]

Great video

[@reyniermartinez8652]

Love seeing the Supra content.

[@goracebox]

Need to do more for sure!

[@LaKuan]

And still has room for growth. Would be nice to see some N54/55 content.

[@MrMendez]

excellent video as someone who considering a custom e50 map

[@goracebox]

Definitely worth it over an OTS tune! However like we demonstrated, the OTS tunes are no slouch and an easy way for someone to immediately start enjoying their cars after a simple flash.

[@MrMendez]

@@goraceboxliterally after watching your video I paid for my custom tune and just finished my last log last night. Car feels like a freight train now! Can’t wait to head to the track to see what she does now. My best time on a street tire was 11.4@120

[@goracebox]

Easy 10s if u got xDrive!

[@MrMendez]

@@goracebox rwd 🥲 somehow managed a 1.73 60ft on 275/35/19 Indy fire hawks so I’m hoping I can do alittle better before needing drag radials…. (Rod sutphin custom trans tune)

[@suprasupra718]

I hate that alarm haha thanks for tip lols 😅 thanks for the tip , dope ass video

[@thomaskrutulis2289]

I’ve enjoyed this series. I know we’re spoiled, but draggy numbers for the stages would be super cool and helpful too.

[@goracebox]

Wish it was our car so we can take it out and beat it around lol, that would’ve been very useful information!

[@reaper8991]

24 Supra MT, never did a stock 60-130mph but sure those can be googled. MHD 93 stage 2 OTS did 10.3-9.8s depending on weather. MHD e40 stage 2 OTS did 8.6-8.4s

[@ZillaFullBoost]

Thats about what I made stock as well and people still don’t think a stock Z can keep up with a stock Supra. “Driver Mod” 💁🏽‍♂️

[@heftygainz]

Just B58 cult trying to discredit literally every other platform but their own lol.

[@goracebox]

Chill ur just too OP 😩

[@CSKeaton.]

VR lol

[@ZillaFullBoost]

@@goracebox 💅🏽

[@Mross931]

Stock for stock the Z is way behind. 380 WHP is equivalent to around 430 crank hp. The z is 400 crank hp while the supra is 430.

[@vanpaz9601]

Now im wondering how much the bm3 stage 2 e50 ots map is making on that dyno, it be pretty cool to compare both stage 2 ots map

[@goracebox]

Would be cool to get a BM3 car in and test it out! We did dyno a BM3 OTS stage 2 93 car a while back and it made similar power as this car on MHD stage 2, but not sure about the ethanol tune.

[@MyFaux]

I'm going "Man why do these guys look so familiar." I pass your shop every time I go to The Shop at Brittmoore. 😅

[@goracebox]

Lmaooo wassup 🤠

[@AZ-hf9ow]

It's more than enough power to put anyone in a jumpsuit, lol 😂

[@ReginaldSharma]

Question for you. Mhd or bm3? Which is better? Can you do a video comparison between those and the b58?

[@goracebox]

As of right now, MHD all the way. Since the release of MHD+ we’ve had nothing but success tuning various B58 and S58 setups on it. Plus the Reflex integration is nice for those running upgraded turbos, port injections, auxiliary fuel pumps, etc. looking for some added safety. Maybe when BM3 finally releases their update that’ll change.

[@ReginaldSharma]

@@goracebox Thank you! Will have to hit you up soon to get something happening with my Bupra. Still at 250 miles tho lol

[@Spinnachpower]

Makes me wanna tune a 740li. A 700hp big body would be dope

[@goracebox]

That would be sick lmao, top mount big turbo when u pop the hood 😂

[@tinthesin1]

I don't want a custom or off the shelf tune. I'm looking for something in between. Do you guys do on the shelf tunes?

[@basedkhalid]

Bro what lmao

[@goracebox]

Bro said on the shelf tunes 😀

[@cdisme248]

​He said no off the shelf toons only ots toons ​@@basedkhalid

[@JarredWoods]

if it’s not off the shelf it literally HAS to be custom bro huhhh 😂

[@katsusenpaii]

so when you say stock tune, that's the supra itself with the bolts ons and the DME not touched yet?

[@goracebox]

Yes stock factory calibration, the DME is unlocked but that doesn’t change anything other than allowing us to flash it! The downpipe even on the stock tune does add a little power compared to a completely stock car, usually about 10-15whp.

[@katsusenpaii]

@@goracebox oh nice, im definitely planning to buy one soon. I come from a single turbo 700whp n54. Looking to find a nice daily that I can squeeze 500whp out of and daily drive. I think the Supra is a good canidate

[@ayyomar]

good video

[@daryldixon322]

How much can the ZF8HP51 gearbox withstand or should you limit the power?

[@goracebox]

In stock form we limit them to 600-650wtq depending on the setup, once built they can take way more!

[@daryldixon322]

@@goracebox thanks how about lb.-ft of torque?

[@goracebox]

Sorry, meant to say 600-650wtq lol! Fixed it now 😅

[@matthewchevres4970]

6870 next gen incoming for your car Alex?

[@goracebox]

Mannnn I can’t even hook with the power I have rn lol, another 50-100whp isn’t gonna make me go faster until I figure that out. 😂 I do have suspension arms sitting that needs to go in and see if we can get a better alignment dialed in!

[@matthewchevres4970]

@goracebox good point brother, i feel you on that! I'm a little worried to because my RWD M340I is coming out of my shop this week. I had 6466 gen 2 on stock trans but will now have 6870 next gen, spool performance stage 2 trans with race converter, vargas cf driveshaft, and ds shaft axles. I'm worried about traction to. I have Kw V2 Coilovers with rebound settings tighter which help running weld beadlocks w/305/45/17 ET street R. I guess I'll find out LoL

[@goracebox]

Lol yea it takes more than a badass tire to hook a RWD car on the street at 800+whp, might need to raise the ride height up and get some suspension mods in there if u spin 😭

[@lcameeno1]

Not a fan of off the shelf tunes... i prefer on the shelf tunes 👍🏼

[@goracebox]

A man of culture 😎

[@kevin-jm3qb]

Wtf is a racebox? Dose it have MHD integration like the reflex+ does?

[@goracebox]

Racebox is us lol, we do the custom tuning using softwares like MHD!

[@long.theasian]

😮😮

[@BulliKid]

How much is the stock turbo good for??

[@goracebox]

Around 500whp on stock fuel system like this one, add PI and it’ll do a bit more. We never really yeet the stock turbos on these cars unless the customer specifically asks for, we always recommend getting fueling and upgrading the turbo if you want more.

[@BulliKid]

@@goracebox is it because the boost comes on in the lower rpms and may bend rods?

[@goracebox]

Yea the stock turbo spools very fast, making lots of torque down low. 600wtq is more than enough to have fun with at that rpm range, but the engine can take much more with an upgraded turbo and it comes in later in the rev range. One of our personal cars is a Supra making close to 800wtq on a 6466 turbo for over 2 years with no issues!

[@BulliKid]

@@goracebox are you able to for example get the biggest turbo you can get and since it’s going to lose some low and power, can you tell the boost controller to target more boost down low to match the power level of a smaller Turbo, and then slowly taper out the booost as you get into higher RPMs is that possible to do on the software?
