Hi all.. i have just fit on a catless uppipe and i have fit on a 2.2k ohm resistor.. every looks fine. The turbo seem to spool up abit faster. but the only problem is its seem like it doesnt reach full boost even after 4k rpm. is there soemthing wrong or issit becos i to get it tune?

Current mod:

TBE
CATLESS UPPIPE
FILTER

hope someone help me.. thanks

exhaust leak? check the gaskets...

i have check and tighten it today...everything is all gd..i mean the power is there... just that it doesnt hit full boost like usually is 14 psi and now its 12 -13...maybe the turbo spool up abit earlier and make it smoother.. that is y i cant feel it? would that be the case?

have you got a boost gauge to check for sure?

And yes a cat less up-pipe will make it spool earlier and it will feel like smoother acceleration.
