Sluggish?

[Turbo97]

Hey, sorry to ask a rather common question I'm sure, but lately my car has been extremely sluggish...it doesn't feel like its pulling nearly as hard as it used to and for some reason when im accelerating just a little bit...i feel the car pushing then letting off, pushing then letting off and its like a tempo sort of thing and when it lets off i see my boost gauge dropping about 3-4 psi...do i have a boost leak? Any help is greatly appreciated.

what mods do you have? And i would think maybe a vaccum leak. I have them and my car is deffinatly slower than it should be.

I have a cat-back exhaust, intake, all intercooler hardpipes, greddy type-s blow off valve, (then turbo timer and gauges)

Sluggish.

New plugs, fuel filter, wires?

If those check out ok, it may be a boost leak. Or a vaccuum leak. Have you done both these tests? when you modify quite a bit, its common for those things to happen.

No I havent, how do i check for a boost leak or vacuum leak because i have a feeling one of these are my problems.

The greddy bov is adjustable...could that need to be adjusted?

because my boost gauge drops 2psi then back up...2 psi then back up...etc...

nothing?

Ah, i think there might be a tech article on how to build your own cheap boost leak tester.

Look in there.
