I have a bad situation, i currently have a -7 pump and last year the stall speed was about 4200 rpm on the foot brake max before the tires spun about 13 psi, this year doing the same test its 5200 rpm on the footbrake, same boost level. The car has gone 10.4 with this converter switching from a -6 pump to the -7 pump. The car ran 11.0s before with the -6. Now at 25 psi boost the rpm drop on the shift is zero, i shift at 6k and 2nd gear and thrid gear it stays at 6000 thoughtout the run, when i hit the lock up in 3rd it drops from 6000 to 4700 rpm, so i am assume the stall is now 6000 rpm at 25 psi boost level, way too much. I have tried launching the car at zero psi 1.67 60' now, 5 psi 1.67 60" and 10 psi 1.67 60', it seems the car revs but doesn't go. I think the converter has gone south. There has to be a sign the converter is no good, could this be it?
