i recently picked up a 07 GT500 and ive been going back and forth on what spark plugs and motor oil to use? i currently have the
NGK TR6 .035 gap
MObil 1 5w-50
heres a lil list of what i know the car has:
American Rcaing Headers long tubes
Borla cat-back exhaust
JLT CAI 110mm
Granatelli xtreme coil packs
Blower has been ported by stegemair
idler pulley and 2.6 pulley
14psi boost
it sounds like it has cams but not 100% sure nor specs of them.
its also been tuned by someone the car is running 12.5-12.8 AFR which is really bad for as much boost im putting down.if any one has any suggestions or ideas on how to get my set up to its optimun potential i really would appreciate it. thanks everyone.

Like others have said, have it tuned by Shaun at AED. Those coil packs aren't doing anything for you, so if they blow out replace them with OEM. The plugs are fine as well, and stick to the 5-50. I've always used Mobil 1 full synthetic in all of my cars.

So this is my update I changed my plugs to NGK BR7EF and gapped at .028 because I fouled my TR6s at .035 dude at AED was who recommended me to go .028 as far as the coil packs I'm not sure if they work or not cause I didn't do the swap. I'm gonna dyno the car this weekend and see what it does with does coils and then I'm gonna put some msd and see what happens. Thanks for the help everyone.

As far as the coils are concerned, don't waste your time with any of the aftermarket crap. IF you have problems with the ones you currently have, just replace them with OEM. Otherwise if they work, leave them there.

A 12.5-12.8 AFR is lean as hell. You need an AFR between 11.0-11.9. Do not get on it, take it in to get retuned before you mess something up.
