My American just flat out beats the pants off of a Cherokee! :] I actually had it out on the highway and put 100 miles on it yesterday. It runs 70 MPH without even breaking a sweat, pulls the mountains in 5th gear without downshifting and if I want to see 80 mph all I have to do is ease down on the throttle. It still has some bugs I'd like to work on, but time will not allow much for thenext couple of months, so I'm leaving it as is. I found my check engine light to be a faulty Manifold air temp sensor and a loose connector ring ont he TPS switch. I've got no check engine light now!
Congratulations again! Nothing like a good hard run to get the sweet taste of success!
