Hi,
I recently upgraded to the apexi power fc d jetro (no mafs). Have a turbosmart boost controller, K&N induction, turbo back 3" SS exhaust and 2 Garrett GT3076s. My issue is I lost all boost when driving a couple of weeks back. Have checked the plumbing for leaks, turbos, DVs, Engine compression.. all seems fine. Injector opening on the dashtop display indicates 10% at 100% throttle and boost is -0.30 at full throttle. No misfires, burning is good, consumption is fine. Please help!:sadwavey:

could be throttle position sensor not working , not indicating to ecu that throttle is open but with -0.30 sounds like boost leak, did you have plenum off when fitting d jetro to fit maf sensors, could be leaking at plenum to engine giving boost leak, weird no boost at all though
