Such a good video! All the information is super informative and love the attention to detail. I think the comments you made about spark plugs definitely apply to my vehicle. Great job Alan!

[@onestepatatime614]

i love the info you try to pass onto your customers, it makes me want to become a customer for my 13 st, appreciate the knowledge instead of just show me the money alot of companies take. my hat off to you sir!!

[@bobbydouglas16]

Thank you for the video !

You don't need a squirrel in your exhaust to prevent boost, but it helps.

[@eddiejennejr4342]

Extremely eye-opening. Thank you! At 42,000 miles this car has turned into a nightmare yes the one pictured to the left. Transmission lost fourth gear I don’t know where it went it just wasn’t in the transmission anymore no broken case no nothing no leaks from the transmission it just disappeared replaced under powertrain warranty. Full bolt on car I did not buy cheap parts . First specialty vehicle first turbo charge car so I didn’t skimp on parts I wanted it to be right. Cobb inner cooler charge pipes couplers T bolt clamps. Turbo outlet coupler to the charge pipe has been a nightmare finally got it to where it stays on now. High pressure fuel pump went out, in tank fuel pump has gone out this is all before 50,000 miles. Excessive blow by. I put the radium engineering PCV baffle panel and billet aluminum PCV valve that got it down to only using a half a quart of oil every two times I drive the car it’s better if I stay out of boost. Constant misfire problems MSD coil packs and NGK IX iridium spark plugs two steps colder, gapped @ .027”. Stock turbo. Get to cut an access panel to access the damn in tank fuel pump because Ford engineers have to make it extremely difficult for the mechanics to work on the vehicles. I know this because I’m a retired Ford mechanic. In this car is extremely pissing me off. When it runs good it is phenomenal, but it is an absolute temperamental high maintenance bitch. I can’t wait to finish my Mustang build. If this thing blows up or continues to give me problems like it is giving me this will be my first and last turbo car. Very lucky I found your channel. The information that you have put out is wonderful lots of help. Thank you

[@alejandropacheco3839]

2 years late but woah… you got a lemon man. Never had any of those issues beating the piss out of 2 that I’ve owned. As far as the trans goes… if you had a gear before and you don’t anymore due to synchro failure it’s still in there I promise you🤣

[@dbwarrior8600]

Found my boost was better with a Go Fast Bits recirc valve, but not mechanical in how, just feels better with boost for me with factory stock map

[@richardlapoint1845]

Probably bc youre keeping the pressure in the system instead of venting to atmosphere. I have that exact recirc valve myself. Only reason i got a recirc was to keep the attention of cops off me, they still look when they hear the sound, but its a wtf is that look 🤣🤣

[@albertomendez8146]

Hey Alan, I am having a issue with my ST...My accessport is indicating a negative reading on ign corr cyl 1... please advice on what it could be?

[@samintrepid]

Did you recommand Alan to put the OEM turbo gasket with the fire ring on the ATP2867R Gen2 for the Fusion 2.0T ? thank you :)

[@TMTMS3]

You shouldn't use the OEM gasket with the fire ring. Just get rid of the gasket and only use the fire ring.

[@dustinmccollister3547]

Wish their was more about the rs

[@runningwildttv3648]

So if I have a raspy noise, its after the turbine housing. Where should I be looking for a leak? Its completely stock aside from Air Intake.

[@Holm.Q]

My ST is tuned and I’m only hitting 19-20 psi 21 if I’m lucky and not to long ago I was hitting 22-23 no problem

[@aksellgallardo3604]

I got -6.00 ignition correction on cylinder 1 what can I do to fix this

[@ryanharris6788]

You gotta put the link to this in emails when you’re etuning an ST.

[@wickedwonderingdream]

What brand for 2 step cold spark plugs and what is best gaping for those

[@EdgeAutosport]

edgeautosport.com/denso-iridium-power-spark-plug-itv24/ are your plugs. If you are running 2-steps down, I assume you've got a big turbo? Check with your tuner on gaps if that is the case.

[@hocusfocusst8244]

“No, it doesn’t have a motor” LOL!!

[@mlukubone7134]

Lol I once switched to eco mode by mistake, even send a video to a local ST group 🤣

[@miguelmartinez8650]

Its probably a dumb question but To check for a boost leak, it would be the hot side and cold side, or just the cold side that i would have to be looking at??

[@EdgeAutosport]

Hot side and cold side often refers to both sides of the intercooler, since the compresses air is hot going in, and cooler when it comes out the other side of the intercooler. If you are asking about the intake vs. the exhaust sides of the turbo, boost leaks will happen on the intake side, anywhere between the turbo and the intake manifold. Leaks on the other side of the engine are exhaust leaks and can also mess with your performance.

[@carlodemarco2148]

Alan, I'm in the UK, plz help me find where I parked my car.

[@leelarkins1321]

Would an ecoboost mustang turbo work in an focus st?

[@alexmyhas]

No it’s twin scroll

[@josuelucianoledezmavega6610]

Hello, i be owner of focus st 2013 and i Just rebuild engine but press ignition botom and do start but no doed combustión and i have code p0300, and p0301 combustion problems in cylinder 1 and 4 do you can give some help please i be seriously stressed, thanks for the help

[@EdgeAutosport]

This is something that needs to be diagnosed by a qualified mechanic!

[@bilboswaggens2975]

Hello I know this video is old I hope you see this lol. but my car is completely stock and I have an overboost code. Should I be looking for a leak or a bad part?

[@EdgeAutosport]

Check your Boost Controller first, you might have a sticky waste gate so clean that up too and make sure its moving alright. It could also be an issue with a MAP sensor.

[@davecozzie1]

Do you ever do the mk2 focus st225 2.5T

[@TMTMS3]

I wish! Don't have those in the states though.

[@davecozzie1]

@@TMTMS3 really! I have one atm.. stage 3 with supporting mods.. so I tend to watch your videos about focus st still.. great videos anyways

[@richardlapoint1845]

@@davecozzie1 yeah we dont get the really cool versions of anything 😂

[@davecozzie1]

@@richardlapoint1845 that sucks mate.. what about focus rs mk2? I believe the focus rs mk2 is the best car in the road for me. It has all the bolt holes already in place so you can fit the Ford kuga 4wheel drive straight on! Which is what Ford intended to do but changed decision last minute.

[@spazzologist]

Anyone ever experience a whistling noise while boosting??

[@hidalgosbulliesdanes8156]

I lent the car to my dad he accidentally put 87 in it and it's limiting boost to 12.5psi and in 3rd it'll go to 17psi but throw out the check engine light that throws the overboost code before when it was on 93 it would hit 17- 25psi easy I have a day running 93 after wasting all the 87 but it still hasn't stopped limiting boost

[@jesuscarrillo4344]

Two years late but I had this problem myself. It was my waste gate on the turbo. It wouldn't close all the way so that 12.5 psi is really 18 psi but the boost is escaping. Go above 12.5 psi and it goes into limp mode. Sometimes, it will just go into limp mode even making 6 psi which would be 12 psi. Got a new turbo and everything was fine after.

Hello, I have a focus st 2.0 ecoboos and I would like to reprogram it to leave 270 hp. I would like to know if I will have problems with the engine. greetings thank you

[@johnboy2436]

Not sure why he hearted your comment and didnt respond, your obviously a first timer wanting a remap. The answer is no.. on a stage 1 remap (270hp -285ish) you shouldnt have any engine issues. Though i cant comment on "your current" engine health before the map. It all depends on the remap but at 270 bhp you will not be running aggressive timing. Id still run it on higher octane fuel, just because you have a tune and to keep knock down. Also dont lug the engine in these cars, meaning dont go full throttle in 5th and 6th.. A general rule is dont go WOT below 3000 RPM. LSPI doesnt occur above 3k on these engines. The answer is NO, you will be fine. Mountune do a 275BHP map standard and its covered by warrenty. So that should also answer your queestion.

[@miguelangellorenzolorenzo6908]

@@johnboy2436 Thank you very much for the answer. At the moment I am testing the production car and it is nervous, that it transmits little on the steering wheel. I have also noticed some understeer and oversteer in the wet. I would like to know how to minimize these things. Thanks I'm very excited about the focus st

[@johnboy2436]

@@miguelangellorenzolorenzo6908 Electric steering will become a treat. I know you want to feel that feedback from the steering wheel but as you drive it. You will come to love it. They handle great. If its understeering and oversteering. Get some better tyres.

[@chriswild8585]

@John Boy hi I'm running a entry stage 1 on a 2015 st no other mods do you need step colder plugs if I wanted to go to stage 1 about 275 bhp also will the engine handle it with heat with stock intercooler. thanx

[@evanbloomfield5287]

10-15k miles before swapping plugs? That seems really often and kinda overkill

[@EdgeAutosport]

Just depends on the application and what you're doing. It's sort of like changing oil. Some people do it every 3k miles even though you probably don't have to. I still do. The more aggressive of a setup you have, the more important basic maintenance becomes, including spark plugs.

[@jesuscarrillo4344]

I just change mine yearly regardless of miles. It's only a 20 dollar bill yearly dude...

[@MrTWINSCROLL]
