Looking for someone with a 1991-99 XJ with the HO 4.0L motor. I am looking for a gunie pig to try out a newly designed product I made. Yes it is performance related, and no it won't blow up your motor. I'm not going to give it away free, but if you want more info please PM me.
Use some of those extra brain cells you have in your head you have and figure out why "it" wouldn't work on the 2000-01 models and I'm sure you could get yourself pritty close to figuring out what "it" is....
