has anyone else had this issue!? maybe you could help me out a little!?

 

Yup, I have some accelerating at partial throttle around 3400 RPM and very low boost if any. Trying to diagnose it now.

 

Can you describe it? Knock or rattle? Im pushing 90k with mods with no knock

 

dont know how to describe it. a very fast paced metal on metal clanking sound as i accelerate just past 3000 ropm and usually goes away by 3500. about the same as laxman. low boosts sometimes also. thats the only time though. i have a borla turbo back, hks bov(no recirc), uicp, act clutch and flywheel, and just guages and junk like that. thats all i know. its the wy i bought it a couple months ago.

 

check your downpipe it could be rattling on the crosssmember,, i had the knocking at low bost and from a stop to slow take off,,, also check all your motor mounts one could have come loose
