Hello all. I have been trying to tune this Jeep XJ for a while now. I am interested in seeing other peoples tune that have Jeep Inline 6 strokers. I would like to do a compare and see what i am missing out. The drive is great until 4th gear, when it seems to lose power in the 2400-3000 RPM range under load. Thank You for your help!
