Work gets in the way of spending the time it would take to learn how to do a custom tune myself..So I am using a piggyback chip that has the 89 prom in it. It was suposed to correct early tcc lockup problem that the earlier computers had, but mine still seems to go into lockup at about 38mph..Anyway, I did drive it without lockup for a while and I like it better with it.1800-1900 rpm @ 65mph is pretty cool.
Thanks for answering my questions, you guys know your stuff..
