Jet Chip Questions(Picture)

[andrew2516]

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?

Try posting this over in the street and performance forum. I think the general concensus is that they are not worthy of purchasing. If you already have one....meh

I think you'll have to run 93 octane, but that might be for the stage II only.
