When I come off the transbrake at 4500rpm on two step, the car bogs and pops back through the blower? I tried messing with the rotor phasing a little but didn't help it. The timing curve starts at 44* ramping to about 36 at 4000rpm then drops slowly to 27* by 6000rpm. 400sbc, 8.87 compression, E-85, Pro Grid ignition. I believe Steve Morris says ignition problems pop through the exhaust but it seems like an ignition problem to me, except wideband stays steady at 11.1 afr? Sometimes it does it a little when I shift to 2nd too, but after the bog it takes off like crazy?
