For you guys running forced induction, what plugs and gap are you using? Any chance on blowing out the spark with 7lbs of boost? Just trying to weed out a slight stutter I have, because everything else looks good now. I am running what STS recommended but anything is possible. Thanks in advance!

 

tr6's gapped at .028. I just had the same problem.

 

im running tr6's at .030"

 

TR6's at .032

 

same as the other guys. tr6's at whatever they are out of the box.

what have you been running?

 

TR6's at .035", but I am going to re-gap to .024", which is a big difference, but it will hopefully tell me if I have found the problem. Any hotter coil packs available? There is a trick to jumping voltage from the alternater, an old GN trick, but I don't want to get that drastic. Thanks for the replys!

 

the stock coils you have are bad *** and will support 20+psi. you can adjust the dwell a couple of ms with programing but i didn't have to do that till about 18psi.

 

Thanks for the info. I'll just re-gap and go from there.

 

Geezus, you run a heat range 6 plug at your power level? That's amazing... I run 7s on my small block and 9s in my big block.

 

no, i wasn't clear. for his power level 6's is what i would use. i used 6's as high as 15psi with no problems. above 15psi i run the 7's or whatever they call them. i have tried colder plugs than 7's but they didn't seem to do anything other than idle rougher. if i make a habbit of going over 20psi i will be going to something colder than 7's
