8 psi max one day 10 psi max the next????? HELP!
 

Ok I went to the track for the last time today.
It was a dissapointing as ever. I could only muster a 14.7 with a .6 re-action and a 2.3 60 ft time.

On a different note, there is no one in my stinkin town that knows anything about 7's that have mods on them. Which leaves me shit out of luck when it comes to tunning my 7.
This brings me to my next problem- Some days my car will hit 10 psi and other days it maxes out at 7 or 8.
I dont know what is going on which really sucks!! I think it could be a wastegate problem but I am not really sure. Also she is ideling alittle rough and I dont know what that is about.

If anyone can help me with the problems listed below I would greatly appreciate it!

Thanks,
Josh

What is the boost controller set to when you only get 7 or 8#? I don't see how you couldn't be making 10# all the time with how open your intake and exhaust is. What kind of gauge is telling you the 7 or 8#?

My boost controler is set to .9 bar. And I am reading my autometer gauge

Not going to say its the gauge but autometer gauges have been known to be off. But with your mods and 1/4 mile time I doubt by much if any. I mean your 60' time could be better but its not bad. I say you defintitely have some sort of turbo/wastegate problem. I say find that problem and fix it and start looking for a fmic ;)

Yeah that is what I was thinking! I just have no one to take it to!! I have to drive 3.5 hrs to get it fixed! The price I have to pay I guess

i'm betting my money the apexi avcr is installed wrong or setup wrong...... try disconnecting it and letting the stock ecu control boost :)

Are you being serious?? Just take power away from the avc-r? What will the stock ecu boost up to?

Also vosko I hear that your fd is almost out all you need to have done is the haltech!! That thing is sweet I cant wait to see the kills that makes!! :)

Ok I went out this morning and I turned my avc-r off. Well unfortunatly it didnt do any good :(
I still only hit 7-8 psi in 2nd? It stumbled in first at like 5600 then picked up again.
Someone please help!! I doubt I am the only one this has happend to.
I think my problem lies in the wastegate but I really dont know. I need help though!
thanks

Have you tried turning your duty cycle up on your AVC-R? Also, what boost is your AVC-R showing?

Also, you're idling rough for a few things:

1) could be old or fouled plugs

2) could be a boost leak

3) could be a blown engine.

I would say that it is #1.
My main reason is because I am running RICH!!!!!
Just because I dont have the car tunned so it is better rich that lean :)

I dont think that it is the engine because at idle I had good vaccum it was right around 15 which is decent.
