Finally got my 91 tune programmed rite I thought. 91 tune red. tq. paddle hold. tran. shift pts I thought read 6250. Whwn testing Iam not sure if I wasnt shifting fast enough or if something was wrong. Seemed to reach a peak and rpms went up and down. seemed about 6100 too fast to look too long. Is it my shifting? also seems like hesitation before the actual upshift. Can shift 4-spd faster with less rpm drop. thanks
