Sorry man just found your post. I gapped mine to 0.035 as well. I went with Brisk RR14YS plugs. I am about to go to O'Reillys in the morning and buy some NGKs and see if they might be a factor in me not being able to hold great timing. Cheap way to check. Don't go larger than 0.035. In fact I'm considering going 0.030 if the NGK's at .035 don't help me hold more timing.Hey guys I'm just finishing up my procharger install and the instructions say to resize the gap on the plugs to .035
One spark plug is a pain in the ass to get to and just making sure .035 is the best sizing
Thanks
