    Drag racing 2011 C6 GS auto with a stall. Need help from the experts.

    I finally took out my 2011 C6 out to the 1/4 mile and wanted to see if you guys could help me out with my automatic settings. I used the bluecat tool but I still feel there is room for improvement. Set up is HCI, 102mm tb, bolt ons, circle D 3600 converter, stock 2.73 rearend, and drag radials. Best time has been 11.17 et. with 1.65 60 ft. @122 mph.

    Not sure why but on the 1-2 shift the rpms go all the way up to 7300 rpms when the WOT rpm is set to 6500rpms. I was hitting the rev limiter in the past but I raised it to 7400rpms to avoid hitting it. If anyone could look over my transmission setting and see if I could try something different I would appreciate it.

    Thanks,

    usually you wait to aim for a lower shift rpm with a higher stall especially lower gears

    So if I want a shift of 6500 rpm enter a commanded shift rpm of 6200?

    6l80s usually only really care about shift mph. Bring that down and give it lead time.
