Tried going from stage 2 (catless downpipe boost creeped pretty bad only drove it once) back to stage 1 with factory dp back on and im still getting around 18 on the boost gauge and boost cutting any suggestions? I can run some data logs of that helps (does it matter what gear never done a data log) all my mods are SF intake perrin LWCP invidia N1 catback and perrin recirculating bov.
Thanks
