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.


usually on a dyno for any auto car you'll see a peak "jump" where the converter locks up that can even be higher than the actual peak power
