High speed run concern

[2001S4CT]

Well it is 245am and I just did a high speed run on the highway. I wont say how much because a state trooper saw me but didn't bother. Well my cel started blinking so since i was going to fast to immediately stop driving, i slowed down to about 60 and shut the car off then back on and the cell went away.

Anything i should be concerned about? Why did it do that?

[The_Jerbel]

Possibly a misfire.

[Kievskiy]

boost leak?

bring that over to ICS man, shit if i paid the amt they ask for stage 3 jobs, i would bring it there if my gas light ever came on LOL. that sounds like maybe something popped off or possibly a misfire as Jerbel said. Maybe an intercooler hose fell off? That happened to me, i was on 95 about to race an STI, and I swear to god as the thought process of flooring it went from my brain to my foot my car completley shut off, i coasted off the highway and lost all my brakes pretty much and steering. lucky i got out safe! my upper IC hose came off.

edit, maybe not since you turned it back on LOL. just bring it to ICS let them know man.

[2001S4CT]

but what i don't understand is that when i turned the car back on I stopped, let the oil cool down a bit and then drove home. On the way home i accelerated to see how the boost was and it was normal boosting at 22. The car is completely normal right now

[AudiSportB5S4]

you boost at 22 on stage3-? you must be running lean city. maybe THATS why your car shut off..... threres no way stock injectors can keep up with 22lbs of boost

[AudiSportB5S4]

for reference, i boost at like 18-17ish on 3-and when i dynoed they did A/F ratio it was almost PERFECT, a tidddy bid lean at one point but it was OK.

How high of a rpm were you running ? If you were close to redline, I would agree with the others that you were most likely misfiring due to fuel starvation. Stage 3- setups are not created to be running at rpms close to the redline.

Or it may be your CATs overheating.

if you weren't speeding maybe this wouldn't have happened lol j/k

On the way home i accelerated to see how the boost was and it was normal boosting at 22. The car is completely normal right now

22Psi on a Stage 3- program isn't normal. I'm guessing that a MBC is in use here. 22Psi near redline probably caused limp mode. Thus the flashing CEL.

+1 on the misfire, my car has done that at high speeds before.

[AudiSportB5S4]

oo dam i feel smart right now. lol yeah but i notice with my VAST software if im holding down 5th gear full throttle im MAYBE at 16psi, no more. bring that back to ICS and say wtf haha.

[2001S4CT]

yes 22 and it tapers down to 20. I should get that looked at then huh?

Mike when I accelerate at 5th i boost at 16 max.
It cant be cats overheating because I have test pipes no cats at all.
And yes I was at redline cause I was well over 150mph

yeah bro, get that checked out. you're probably running lean as hell. tell them youre hitting 22-20 which is as people are saying a little too high for stock fueling.

[ThirdStrike]

flashing cel usually means multiple cylinder misfire..

[The_Jerbel]

Running lean and misfiring. That's my guess. Maybe they gave you a tune for a full stage 3 by mistake??

Take it back and get them to reflash the ECU with something a bit more realistic for 3-
