A VATS bypass will NOT work in this application. VATS bypass modules can be designed to put out either a 30 or 50hz square wave signal which will bypass VATS on an f-body motor and lots of older GM stuff. Truck, Vette, and GTO LSx`s use a serial data signal which cannot be bypassed, you have to turn the VATS off in the computer. I have heard that it is possible to use a tuning program (don`t remember if it was HP Tuners or EFI live 7) to change the VATS in the computer to the older style square wave signal instead of the serial data signal. But if you are in there anyway you might as well just shut the VATS off completely.......unless you really want the extra security.
