So where are people really going to see the biggest benefit for this? Sled pulling? Kinda new to this whole diesel/allison trans world and trying to understand the need for this:eek:....In tow/haul mode, doesn't the tcc lock up in 2nd anyway?

For the non sled pullers, and DD/weekend warriors, what kind of benefit would this have?

I would like to know this aswell.

So for the guys running this controller, has anyone tested at the strip to see if their vehicle is quicker with this locked, or even feel quicker on the street while doing a standing start WOT run?

What about peoples thoughts on better fuel economy having the converter locked more often?

I picked up ET from it. MPH dropped. Your not supposed to keep it locked for too long so it won't work for better MPG.
