1) I agree with KT: go with the OE gap of 0.054" for normally aspirated.
2) P0602 is a "Control Module Programming Error" and that fact that it happened following someone installed a new dyno tune suggests that the programming had errors.
P0430 is "Catalyst System Efficiency Below Threshold (Bank 2)". This is telling you that the rear O2 sensor on the driver's side is saying that the catalytic converter(s) on that side are defective. If you've got an O/R pipe or a set of high-flow cats in place you may get this code unless you use MIL Eliminators (O2 sensor filters) or have the code disabled in the tune.
Get these two (especially the tune and P0602) looked at first, clear the codes and then see what happens with P0300 (misfires).
thanks guys , i think i figured out what caused the p0430 when i got home i poppe the hood and noticed the pcv valve was not pushed in all the way so i cleared the codes and this morning when i let the car warm up i still got
p0602 and p0300 my tuner is looking at it on sunday so i hope he figures it out i really dont know what to do for those codes after changing the pugs i cant find a miss by listning to it ... anyway thanks
