I have tried three times to diable the CAGS 1-4 skip shift on my 2009 Corvette manual 6 spd and then install the tune. Each time, i get a CEL and a code 0803 1-4 skip shift.

What am I doing wrong?
Thanks

Hmmm...you should not have to change anything, it should be off by default in the tune.

I loaded the Diablo tune and still got the shift light, so I went into the performance tune menu and turned CAGS off. Now, I get a Check Engine Light (CEL with P0803 code, 1-4 skip shift) everytime I start the car.

I just got back into the performance tune and turned the CAGS back on and loaded it, but need to see if I still get the CEL.

just having the light does not mean it will still make you shift into 4th.
