When Boost Rises, 02 Readings Fall.

***ZGN*** · 02-17-2008, 06:23 PM

When rpms near 4000+ and boost starts to rise, car stumbles out and has no power. on the PFC O2 is reading .02 when this happens.
As long as there is no boost, the car runs perfect. I have a few ideas but thought I would post here to kick off the forum!

What do ya think?

My setup is as follows:
Apexi Power FC + Commander
Profec Type S Boost Controler
BNR stage 3 Non Sequential
Streetport
850/Bosch 1600cc Top Feed Injector
MSD6A
Nippondenso Fuel Pump (known as the Supra TT pump)
3" downpipe, Midpipe, No Cat, PFS exhaust
PFS Intercooler / Airbox
ACT / 9.5 flywheel
Fuel filter 10k miles on it 3 years old.

Thanks,
