i WAS running ac delco cr42ts plugs gapped at .032"
car didn't exactly like that...i think those plugs were too cold for my stock motor combo...went to cr43ts plugs gapped the same .032" and it really likes them...i run about 25 psi on a dual nozzle alcohol system as well...i finally got it (i think) to where it doesn't get transitional knock...i just turned down the spray on point to 1-2 lbs of boost! and amazingly the car doesn't bog...
