BTW OEM GSR is P72. P28's can be chipped to run p72 Software however a stock p28 will Run a GSR quite crappy.

- Sun Oct 17, 2010 9:59 pm #218709 The P75 ecu will start and run the gsr motor. It will not feel or act anything like an LS though. The fuel and timing maps will be off, you might also get detonation from the sheer fact that the GSR has a higher CR than a LS.
