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 here.

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.
