Ok...I bought a 2000 XJ off a guy and he gave me a Jet chip with it but it wasn't installed. I'm thinking about selling it unless somone thinks its worth keeping. I installed it and didn't notice much of a difference...this XJ has 37"s and 4.88's though. The sticker on the top of it was old so there is no part # on it.
Does the jet chip control shift points?
Anyone know if this is a stage one or two chip?
Also anyone see any MPG increases with these?
