I took the motor out of my 86 Iroc. A 305 TPI.. and rebuilt it and it took the place of my 350 in my truck. My truck is a 88 350 TBI. I kept the TBI on it and put the 305 in with the camaro cam. I got it to run but it with a bad idle, and am finding that it's hard to tune, and I don't believe that its getting good gas mileage when I do drive it. Could this be a chip problem? Does anyone have suggestions on where I should go to get a chip? I heard from some of the postings on here that hypertech cux, and someone else says that these "fastchips" are pretty good. This is the first time I have done this so any and all help would be greatly appreciated!!
