Hey guys, recently my car was tuned and we came to a issue where my car will break up extremely bad when i do a 3rd gear pull..The boost spikes to about 34psi.
But if i do a full run 1-4th, the car runs like a champ (No break up)
My current setup
Evo 9 turbo (Ported)
Stock Exhaust Manifold (Ported)
Stock Intake manifold (ported by buschur)
boomba 65mm tb
Br Uicp
tial bov
Ams Intake pipe
perrin filter
Strictly Modified Fuel rail
1050cc fic Injectors
Ams knockoff Fmic
Ams licp
megan o2 housing
Invidia 3" exhaust (no cats/no res)
fp4r cams
arp headstuds
NGK bpr7es .022 gap
e70 (winter blend) tune holding 28 psi

My car did the same thing when I blew my turbo. The exact same thing. I would check your shaft play. I cracked my divider and splintered my shaft pretty bad... 1st-4th no problem but if I loaded up in 3rd or 4th it would knock throughout the powerband in odd places and couldn't fix it. That's how we realized the turbo was shot, bad!
