New to sight, had buicks in the late 90's. Had kids sold Buicks!!! Nuff said. Now have a 87 GN. TE44, 42.5 Injectors (can't tell brand), 3" SS downpipe, 3" ATR exhaust, Walbro Pump Hot Wired, Turbo Tweaks street chip. Stock Intercooler. OTC 4000e scanner. Ok now here is the issue: At around 7bs of boost, the car starts surging and the O2 volts go from 1.02 to 0.01-0.00 pretty quick. I am getting no knock or timing retard. It has an adjustable FPR set at 42 bs base. One thing I can't see is what FP is doing when this is happening. The MAF is aftermarket and the readings seem low from what I remember. Does anyone have any suggestions??? Also, help me remember the values I should be getting. TPS is .44 idle-4.83 WOT
Thanks In Advance
