Coil Question I have an 02 LS1 with a stock bottom end and a Texas Speed and Performance cam kit. Large cam with full long tube headers, 3" Y pipe and an SLP Loudmouth cat back. I am looking to add the coil packs that Texas Speed offers claiming up to 15% more power. At one point would I be looking to go to larger fuel injectors and do you need to go with a larger fuel pump right away? Would I need to re tune the computer? I just had it done using HP Tuners. In addition, what effect would a larger intake and throttle body have on all of this.

leave the coils alone if its running fine, if you have a bad coil then replace that coil. focus your money somewhere else. like intake or maybe true dual exhaust setup itll be money better spent.

There is so much energy in the stock ignition, such short wires and eight individual coils, it surprises me that folks still believe there is anything to be gained from a coil upgrade on the average street application. Like said above, skip the coils unless you actually have a bad one.
Not enough data above to know if you need an injector upgrade but, if you do, a retune would be needed for such.
