Just want to note I've pulled best strip times by shifting before redline. On non hybrid mk7 systems, most of the torque is a hit and scream type attitude. As in, baam and then a diminishing hold. This is conducive to 5.4 maybe 5.5k shifts instead of blowing past that redline. Watch a flash tuned car on the dyno... They drop power FAST .
my is38 on e85 holds power to redline
