I got issues with a customers car. 1.5 seconds rpm stall on the 1st to 2nd gear change. Its a glide with a 4.57 rear gear & 29.5x10.5x15 tire. The car is 3595lbs. ETs are junk cause of this! I tried everything that was said on a thread on the trash or be trash forum, from up the shift point to adding timing at that point & did absolutely nothing! The car goes 138.11 at the 1/8 to 173.58 at the 1/4 with this issue. The car is shifted at 8700rpm normally & went to 9000rpm. The timing is 19 total at that point & put 2degrees back in for 1 second that's a total of 21 with a big jet on a single fogger. The 02s are reading 12.8 so i don't think I'm off on the tuneup, it wasnt lacking power at that point. The torque converter is slipping 6% at the finish line. The rpm drop on the gear change is 1300rpm, it drops to 7400rpm every time & it sits there for quite a long time, when it decides to recover it goes through at almost 9100rpm at the finish line. Does anybody has any suggestion on whats going on with this thing? Its a customers car, not the one in my signature just in case your wondering!
