won't spin tires
I had the same problem about 1 year ago. My problem was when i got my tranny rebuilt i asked the builder if he could make my converter a 2000 stall; Well turbo buicks factory stall is about 2200 rpm, so i actually got less converter stall and it would not let the turbo spool up enough to make any power. I got my extra 3000 stall converter and installed it; let me tell you! night and day difference. So in conlclusion I believe you don't have enough stall.
