Need LT1 OBD1 A4 Shift help please. Datamaster file

Good day. I am working with a 1995 Z28 A4 stock block with only a sts turbo and a 2800 stall. Car seems to shift 1-2 fine but 2-3 and 3-4 are not right. Lots of rpm and no increase in speed. Like it's slipping. Any suggestions? I installed a stock 1995 A4 flash that Shoebox had posted.

Btw, the car shifted fine before I switched back from an OBD2 to an OBD1 computer. I switched so I could tune with tunercat I have and do not wish to revert.

Thanks for any help.

The OBDI pcm is not as fast so the pressure may be slightly lower when running it. Sounds like your 3-4 clutch pack is likely on its way out though.
