Can you buy performance chips for the 2000 XJR?? If so, who makes the best one?? Power gains??

Thanks Gang,,

Paramount Performance and Eurotek have i think the most cost effective.

I would go with Eurotek because they have a ECU and pulley package to gain 65hp and 100tq for $1700. Paramounts ECU gains 25hp but costs nearly $1000.

 

Fyi, there are no chips, but reflashes of the ecu with new software
