Back to working on this beast. replaced coil, wires and plugs. The vacume booster failed so replaced that. car runs really good, still dosent like boost. Spools quickly and staying under half throttle and up to 8-9 lbs of boost were all good, more than that and knock jumps in...alot.
chip says 20-18 on timing. if I lower the adjustable timing in the chip is that only for WOT or does it lower it all over? winter is coming so will probably send chip in then to be burned for exact combo in car.
