So my pace car, which is bone stock, is now showing about 2 degrees of knock, and the gas mileage dropped about 2 mph. I think that they dumped regular grade into their premium tanks. How do I prove it?
i dunno Kyle, it is bone stock, and i know people that run reg in their stock gtp's and have no probs. but then again, they have probably never scanned for any kr.. so ??????
