Currently i'm running 4 jacobs c-4 coils with a HKS TP.. last year i was having some reving problems wether it be wiring or compent i was unable to rev past 3500 without some serious backfiring.. its a single turbo with a microtech. the body wiring should have no effect on the actual motor right? i know dumb question but still gotta ask. The wiring from the microtech was wired by me and runs the twin power to coils? i'm trying to start over even if i need to buy new parts/components.. don't have the stock coils or anything like that.. any help would be appreciated.. thanks
