    fixing shifts after converter and gears

    Just had a 3.42 gear and 2800 stall installed in my 07 A6 Corvette. There is a very basic tune on there currently which is not allowing it to shift properly at WOT, banging off a rev limiter.

    I've spoke with a few guys and did a bunch of research and was hoping anyone can check over my work or give any additional pointers. Thanks!

    Could it be that after you switched to 3:42 your full throttle shift speed is set to high?, only when full throttle shift speed AND full throttle shift rpm is reached will it shift at WOT

    With an auto I believe that you must change the gear ratio setting in the PCM to reflect the new 3:42's. HPTuners will them automatically change the shift points (MPH and RPM).
