Finally past the 36000 mile mark and ready to give it a bump.. Going with a steeda pully, JLT cold air, Cobra jet with the two Throttle body, Tune and Dyno... Its going to be expensive but was told I'll add 100hp. Questions Does anyone know if I need to upgrade anything else so the Shelby can handle the mods? Will it destroy gas milage or will I not really notice?? Thanks for anyones help or advice.. Best Mikeyp
