with my setup i have a dp plog hv3 and 180 t stat and ran a 15.4 with stock pcm but if i had to chose id do pcm first and just put a cone filter on the intake tube thats all i did and it works good i just take out my driver side headlight at the track to get cold air hitting it but ya all the heat sheild ported tb are useless on a stock car id save that till u are more modded with all the stuff i have plus rockers and pcm then id do ported tb and as for msd coils its the same as oem ur just paying for a name if u want them it would be just cosmetic they perform same as stock
