Cobaltss,
My tune actually follows your RDR tune quite a bit except for the PID tables, OS tables, Opti TQ, DALs, MAF settings. Did you mess with the PID tables in that tune at all, or were those left stock from your cobalt? Mine were quite a bit different, and I'm not sure if that is from the tuner I originally got the tune from, or if it was just different since I'm running a solstice.
