I HAVE A 03 IMPALA 3.8L V6. I RECENTLY PUT A TURBO KIT W/INTERCOOLER IN IT SET AT 10PSI RUNNIG AUTO LITE 103'S @ .040. RUNS GREAT. I HAD MY CAR RETUNED WITH 15 PSI. MY PLUGS KEEP BLOWING OUT/ MISFIRING. I HAVE NGK TR8'S IN IT GAPPED AT .035. I'M THINKING IN NEED COLDER PUGS, BUT I DON'T KNOW WHAT TO SET THE GAP AT. CAN ANYONE HELP ME???? :(
