Well dealer says my Big Bad superchip may void my warranty. Well they said my truck only showed 4 gallons of fuel used but my hours were fine. They said that if chrystler asked them ?s @ my hours and ( ? fuel used) they would know i had a programmer on it and might void warranty. Anyway, i have a knock that isnt an injector, maybe a broken wrist pin or something else. Truck runs fine and still has good power n ot smoking or ideling rough but it is knockin i little louder than an inj. knock. WHERE can i go to get it fixed quick, if my warranty is bye bye, I live in So. Illinois. I dont mind driving a few hours away if i can get it fixed as quick as possible!!!
