TBI Whipple HELP!!! Need some help with a Whipple problem?? 95 TBI 383 Stroker .. Cuts out and
backfires around 4000 rpm's. Has a helper pump, late model tbi big block injectors and fuel pressure regulator. I am guessing the one that comes in the kit. Fuel pressure is steady @ 28 psi until boost and climbs to a steady 35 psi and doesnt change before and after cutting out. O2 sensor shows lean at the time of the cutting out. o2 sensor reads between 900 - 950 just before cutting out the changes to below 20 when it cuts out.
Thanks for any help!
