Deleting the security sytem will get it running but not always driveable. Only certain computer os will work on a swap. 8 speeds are much harder to get working than a 6speed. I have only had about 3 successful 8 speed swaps. If you have the orginal tcm for The 8 speed it should work. I can test both computers at my work before hand. If you get everything working together you can get performance like this...

I have a company doing my harness and reflashing the ECM and TCM. I do have both CPU's. What is your experience with the fuel system? Do you need to use the higher fuel pressure pumps?
