Default XJ8 Question
I got a 99 XJ8, i need some more power and was thinking of getting a chip for the ECU. I was wondering if anybody could help me find one.

Those chips are generally a waste of money.
I have 2 of them and neither of them do anything that is noticeable.

The ECU on the car will learn whatever is attached to it.

I suggest doing it the old fashioned way: Allow the engine to breathe.

Intake/exhaust/etc....

The ECU will learn the upgraded parts.

If you really are interested in going the "chip" route, then I would look into a shop that can reprogram your existing ECU. This takes special tools, a knowledge of HEX, and somebody that knows what they are doing. This is usually done on a dyno.
