2.73 gear, and high stall shiftpoints
 

trying to tune my car with this converter finally. at the track I had been hitting the 1-2 revlimiter under WOT. I've done everything from lowering my shift MPH to raising and lowering my shift RPM. I'm not positive but I think my converter may be slipping to redline before the shift. I believe i lowered my 1-2 shift as low as 34 or 35mph and it still would shift late (rev limiter raised also) should i go lower on the MPH?

how would you tune the lockup points under normal driving? my car doesnt want to lockup in 4th gear (over 60-70mph). ive mimicked a tune I downloaded online but that guy had a cam.

any help would be appreciated. thanks alot guys :)
