So Last night I was cruising around and gunning it from time to time, when I noticed that my turbo was lagging like crazy. I had the boost set at 20-22 psi. Here's what happens, when gas is applied, the boost would jump to around 12-15 psi and would hang there for a second like it was spooling up, then the boost would kick into around 20 psi. I've never had this problem before intill that night. I was wondering if anyone else had this problem and could shine some light as to what might be going on. Thanks!

PS: Someone suggested that the boost solenoid might be malfunctioning.

do your rpm seem to shoot up faster than your speed?

could possibly be your clutch kinda hard to say though

 

happened to me ended up being the clutch slipping

 

Yeah my rpms are doing it. I talked to some guys and they are saying that my clutch is slipping. I've been having clutch problems that same night.

Any suggestions for a replacement clutch?

 

^^^^Twin Exedy and call it a day

 

Exedy Twin HD and please fix your mods - they're terrible. You have a VTA BOV, full intake system, EBC, fuel pump, and stock exhaust with no tune? Awful.

 

Agreed.

 

Double agreed +7

Exedy Twin HD is a great choice too.

 

Yeah I'm working on it right now... I bought the HKS with the recirculation kit but the recirculation kit is not compatible with the injen intake system. It appears that I'm going to have to cut part of the blowoff valve pipe inlet to get it to fit. I just ordered a ATP gt35 turbo and I want to get cams and cam gears before I get the tune. For now, I'm going to get a Apexi fuel control and tune it so I can run it safe. And once I have more monies, I going to take it to Jester tuning.

The logic to me is, why get a tune so soon when I'm throwing on mods about once every two weeks.
