Hi guys,
I have an ECR33 with very minor mods (exhaust, I/C, metal intake, 10psi actuator, splitfire coils, bosch 040)
It will run fine at WOT out to redline at 10psi with no hesitation whatsoever
However, under part throttle at low revs the boost comes up and it surges/ hesitates like it is hitting a boost cut.
It mostly happens when I change gears and get back on the gas = frustrating
I have cleaned the AFM with AFM cleaner and checked all the hoses/clamps. It has NGK BCPR6ES at standard gap.
Anyone have any other ideas of what it might be?
Cheers
