I'm taking my car back to stock, so I won't need this '09 GXP 5MT ECU w/ GMPP tune and the 3bar MAP/TMAP sensors/pigtails.
If you've been looking to upgrade, here's a plug 'n play solution, no extra ECU or trip to the dealer to get the flash necessary.
No pics yet, as the ECU and sensors/pigtails are still on my car, but I expect to have everything off next week.
Note that this will *only* work with an '09 GXP 5MT car, not any earlier year or transmission.
