so i fixed my dp.. lol, and i got the o2 sensor bung put in by the flange underneath the car and i put a new 1 wire o2 (my ecu has heated o2 disabled) and everytime i get to 10 psi it feels like im hitting the rev limiter, my boost cut is at 9 psi but ive had it up to 12 before with no problems at all

just confuses the heck outta me.. it idles a little lower also and when i take off it has a slight miss but once im going its fine..

im running the d15z1 with a y8 head 440cc dsm's with ngk 2 steps colder race plugs gapped at .32

any help would be appreciated.. also no cel...

well.. turned it down to 8psi and replaced my spark plug wires cuz they were kinda messed up.. its fine now.. but slow.... lol i called my tuner and asked him for a 3 bar map cuz i was maxing the mapsensor at 12 i guess ( studder every once and a while) hes all " what do u wanna blow that thing up???" hahahaha..

idk 8:1 compression is low.. to low for only 8psi.. will be street tuned soon with 3bar map:TU:
