I too can already lock my tranny in any gear on my LB7.
Its really fun with a smoke tune. You can really pour the coals out.
Then I tried getting a bone stock Dmax to smoke.
Took out my dads 03, did 35mph and locked it in 5th. Then pinned it. Ive determined its impossible to get a stock DMax to smoke.
My version is old. Its from last June.
