    C7 A6 Callaway Supercharger Speed limiter issue

    Hi,

    we have a C7 A6 with Callaway Supercharger in our shop and the cusromer complains the car running to a Speed Limit at 187mph.
    in the scanner i can see Torque Source Trans S limiting but i cant find any table to remove the limiter.

    HP Tuners Support was looking to the file and told me its a Tuning issue.

    thanks for help.

    And after looking at the trans table I will say that I bet it is hitting the rev limiter in 5th gear.

    I think he means your shift points are calibrated incorrectly so its not shifting.

    quick and dirty way is to change the conditions to 8k.

    Does not matter..... A6 will not shift to 6th gear under WOT. Only way to go faster is with a taller tire or higher rev limit or change the ring/pinion.
