Ok so I am trying to figure this one out and I am stumped. I drive my car normally, and the rpm will go up by about 1000 every time I give it any sort of pedal. Doesn't matter what speed or gear it's basically as if you were riding the clutch. But it happens even if you are doing 65 mph and accelerate using the cruise control buttons. Is this clutch or ECM/timing? I have no clue. Also there is no CEL.

 

Maybe a boost leak

 

I think your clutch is starting to slip

 

Clutch is on its way out.

 

i couldnt think of anything but the clutch

 

I was going with clutch but it seems odd that I have no other issues outside of that, shifts fine etc. Oh well I need to upgrade any way since I am going to mod it here this week.

 

Yea sounds like a slipping clutch. It's like the rpms are shooting up but the car isn't really accelerating and then the rpms drop back down and the car accelerates like normal? If so DEFINITELY a new clutch is in your future. How many miles do you have?

 

just hit 60k on miles, what are inputs for a decent clutch for 400-450hp

 

Exedy twin disc

 

Clutch for sure. If you want to test it again, go about 65 on the freeway and leave it in 5th. Floor is and see if it slips when boost comes in.

 

^ I agree that's how I knew it was starting to slip and I also noticed a difference when and where my clutch would engage.
