Im running a streetported FC T2 running a T04E on HKS F-Con Pro (piggyback, stock ECU runs OMP etc) and due to NGK10 plugs, rich mixtures, water injection, and loads of boost, missfires are a serious issue for me so want to upgrade.

I can get great deals on Nology stuff, and they do Profire coils and Powercore amps, but I have no idea if they are any good? Seems to be very little info.

Other option would be Summit stuff, which ive been told are very good and actually the same as Mallory stuff- they certainly seem to have the same spec.

I presume its worth upgrading from my T2 coils rather than just adding the aftermarket amps?

Summit stuff is fairly cheap so 4 coils and 4 amps would be within my budget, but I still dont want to if it is utterly pointless as it just adds work/clutter/weight.

Im getting conflicting advice what would be my best option, be it a single leading amp upgrade or 4 uprated coils and 4 amps, or anything in between, so I thought id ask the experts
