Why the **** does my damn evo have to be so inconsistent.

I got back from TT running great pushing 2.06 bar consistently in almost every gear. Now the ****in thing will barely hit 1.6 most of the time, and I have no boost leaks!!

My car is about to put me at wits end, I've been fighting it for 6 months or better trying to get it to stay the same and produce good power. Looks like thats impossible for me.

If it doesen't straighten up for me soon I'm gonna consider it possessed and sell the god damn thing.

 

Could it be that running 30psi on a daily basis with the stock turbo doesn't work so well?

 

what are you using to controll boost, what mods do you have

 

Just shy of 400whp/400wtq at TT:

AEM EMS(speed density)
PLX M-300 wideband o2
Greddy Profec B2
HKS 280
10.5 hotside
3" TBE w/ test pipe
Homemade upper IC piping and intake
Greddy Type RS BOV
SMC v2 alky

 

Could it be that this is happening b/c you got tuned at TT?
Just an observation.

 

How do you know, have you tested the system? Or are you saying this merely on speculation because you don't hear any?

 

TT has done an awesome job for me many times now. The car ran great and perfectly until about 3 days after something has gone awry(through no fault of theirs).

I pressure tested the system today and fixed one small leak that I had, however it is not any different.

 

The turbo cant hold that much booost day after day, I bet you run the car that way for a month then check shaftplay you will see quite a bit of play.

 

The turbo will be fine for longer than a month. This isn't the first time this car has pulled **** like this. Thats why I say I'm at my wits end.

 

i would point the finger at the profec b, have you tried using a different boost controller? everyone that i have seen has been inconsistent at best...

 

tis what I"m working on. Trying to go back to a MBC. Going to likely just buy a whole piping kit too, but I'm having troubles finding on in aluminum for less that 600 bux.

 

30PSI on stock turbo? WTF?

 

I ran the profec b on my eclipse for two years at 25-26psi on an evo III 16g. Never had any problems.

 

bear in mind that guage is not worth a ****. The AEM is logging 28-29psi.

 

i am just sharing what i have seen and experienced...
