Big S/O to the good folks at Horsepower Addicts for inviting me back up to strap the 6th Gen on the dyno so we could get a good number with the converter actually locking. Used HPT to manually lock it and made a 5th and 6th Gear pull as 6th Gear is the 1:1 on the 8L90 transmission.
582/518 were the results in 6th gear.
Car has already been 10.16 @ 134MPH.
