ok just made my own boost leak tester.... only found one small out by the iat.... fixed it... took it down the road still nothing.....

it still shutters bad when letting out on the throttle...also when u give it full throttle expecting to hit full boost...all u here is a loud pppppssssshhhhhhh.....(sorry only way i could describe it).

again...there are no boost leaks now.....so only thing i can think of is its the bov...or wastegate...which one would u start with.....also what are good replacements..

thanks again for all the help
