Have an 02 Gtp Around 120k on the dash. Just wondering if what my car is doing at my mod level is normal or not. Current mods that actually matter are 2.5Inch ZZP Dp,K&N Cold Air Intake,Iriduim AutoLights 104s. Have a 2.5ZZP Catback and ZZP wires and coils But i know those don't do much in terms of KR. Im on a 3.4 right now and seeing 2-3 KR Sometimes less. Have a 3.6 pulley too i usually run That i almost get little to no kr on. Just wondering If a Tune would help? I also Have some SD Headers I'm going to be putting on, hoping that helps too. Any Thoughts Are appreciated very much. Thanks!![]()
