Boost Creep
 

Hey all~ new guy here

I've got a 99 GSX with the following mods-

Big Evo III 16G from FP
Evo III o2 housing
SBR front mount intercooler kit
Tanabe G medallion exhaust system
HKS ssq bov
DNP manifold
FP 4" intake pipe
walbro 255

anyhoo i'm running at 15psi. and im getting creep in 1st and 2nd gear. it will hold 15psi until I get to about 5000-5500rpm and it starts creeping to god knows when~ in 3rd,4th and 5th it holds fine. People have been saying to port the housing and it should solve it, or should I just get bigger injectors and deal with the creep? :confused:
