my 2011 is not an auto, but for some reason they dyno strangely low torque numbers but top end hp is identical to manual cars. i think the dyno is being fooled by the converter lockup. you know gear ratio is calculated based on induction pick-up readings from a cylinder and roller speed.

there is probably a lockup sequence that causes the gear ratio to be incorrectly calculated and thus torque and hp numbers incorrectly calculated.


just my opinion. the tune may be fixing the lock up by keeping it from locking throughout the run. multiplication and torque converter slip magnifying the torque gains. my opinion is it gained top end.


if, in fact the gains are real, its going to make the auto cars bad-ass. its gonna be months before we can say what a 2011gt will make tuned.
