it should be tow haul. but the difference between t/h and no t/h is that when the t/h is on the t.c. will lock up in 4th gear then straight to 5th gear locked up as compared to only locking up in 5th when t/h is off. i like to have tow haul on when i race but thats just my opinion

On your guys's transmissions doesn't it also give it a little more line pressure for firmer shifts.

Full throttle in tow/haul vs. no tow/haul feels the same so I just leave it off. The only time I notice a difference is when I'm cruising around and obviousy the engine braking.

It all depends on the tune you have, most of the time the race tunes already have it programed so you are working against it. Just leave it alone and let the tune do what it was written for.

Plus I think the new electronic trans deal more in TC lockup vs, line pressure.....
