    G6 speed limiter

    I tried to remove the speed limiter on my friends G6, I changed the speeds for him from the stock 115 to 150. He said when he attempted to go past 115 the speedo stayed constant at 115 and the rpms stayed constant...what am I missing, do I need to change the fuel and spark also?

    Did you set the source to calibration or did you leave it GMLAN? 99.999999% of the time that is the issue.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    I just went over the file, and I believe my screw up was where I left the second speed limiter set to 114 :/ and only changed the first limiter. Attached is the stock and modded file, if you want to take a look. The trans shift times have been changed as well if you wouldn't mind taking a look.

    Yeah you set the source up correctly so its likely one of the speed limiters you didn't move up.
