in need of the factory gm stage one tune for my car i just bought it and it has the stage one kit on it and i dont have the serial plaque
the car was detuned for some reason i took it into chevy so they can retune it and they cant due to not having the gm performance serial plaque due to aftermarket hood and stock hood is gone i am the second owner and have contacted the 1st owner and he scraped the hood
so does anyone have a tune for a 2010 cobalt ss with 5 speed stage 1 gm turbo kit ( the 3 bar map sensor kit)
