coil packs/Injectors
 

I was just wanting to know would it be worth my while to upgrade my coil packs to the MSD coil packs for my 98 gt? Also would it be worth it to put 24lb injectors in place of the 19lbs, and would I only have to calibrate the MAF?

P.S
Eventually I will be adding nitrous.

Upgrading the coil packs would help but itll be minimal unless the ones you have are shot. With what you have done to the car now, there wouldnt be any reason to upgrade the injectors. Once you add Nitrous you probably would.

Ok but im not sure if there going bad or not. what would be some signs of them going out?
