Dyno Q
 

If and when I get my car on the dyno.. Will tuning it help with the jerky feeling I get when boosting then lightly letting of the throttle. The car jerks back and forth pretty bad. And can my problem with reving then dying when the rpms fall down to normal like the engine cant catch itself?, flywheel from what my cousin and i are thinking.

This is probably a really vague description.

Sounds to me like you have your blow-off valve vented to the atmosphere instead of being routed back into the intake track.

nope it's a recirc and if I think about it don't think it's only when i'm boosting. sorry for the error.

Re: Dyno Q
 

it could possibly a small hotside... on my old 50 trim and crusing at 70, if i were to tap the throttle i would see boost and the car was really jerky... like as bad as hitting the gas from a roll in first gear.

Get a dyno-tune then, those fix a lot of things.

Re: Dyno Q
 

until I get a new clutch can't do it.

Re: Dyno Q
 

I had the exact same problems, and it was the blow off valve fluttering. what kind do you have? even if it is recirculated, I spose it could make strange problems if it's not closing when it should.

G T-s

What is a GT-s? It's probably your blowoff valve, my evo did the same thing after installing a Forge, as well as a greddy type RS. Try a different BOV, it will help.

Greddy Type-S, and after driving it today yea it is my bov. What exactly is the problem going on?
