Ok so i installed a FR prostreet stage 1 turbo kit on my car along with a 3 inch exhaust, car is being tuned with hondata, but im having a boost creep as soon as the car hits vtec, i changed the wg spring for a new one (.5 bar) and it still happens, the boost cut at hondata is set at 9 psi.
I check the vaccum lines didnt find any leaks, any suggestion guys?
TIA

 

help?

 

try a different vacuum source for your wastegate, and if youre using a small line with small fittings try using larger ones
