Recently purchased a 99 gts need help
Everything on the car works great but I am concerned that the few mods that the previous owner had done are not aiding in hp increases and possibly lowering hp. The mods are TNT exhaust, K&N direct air, and TNT throttle bodies. I wonder if this is too much air flow to an unmodified engine...- redwhiteviper
