LS2 swapped 96 impala ss transmission issue I'm tuning a 96 impala for a friend of mine who did an LS2 swap from an 08 TBSS. He had his stock wiring harness modified to work with the LS2 ecm and tcm. He's running his original 4l60e. Leaving the transmission speedo tables stock, the computer is reporting 158 mph. This is one area I've never ventured. anyone have a clue on what I need to do?
