alright so when im cruising in 5th gear then get on it fast the boost guage will flutter back and forth when it hits 26 psi. but when i slowly get onto the boost and bring the boost up slowly to 26 it holds there perfectly fine. Whats going on here? is this an indication of a boost leak or what?

 

Sounds like it to me. Mine is opposite. If I ease onto the boost at anything over 80mph in 5th, I'll get a bit of fluctuation because it's not making enough pressure for bov to stay open or closed....... but if I floor it, 26psi STRONG.

 

Also check you piping of course.

 

pipings all good im thinking i might have a boost leak at the throttle body seals because i dont think they were ever replaced and the car now has 80k miles on it and i heard there the first to go. i hafta do a boost leak check i guess
