Duramax tuner

There are guys here that I know that are running the Banks Derringer controller on their L5P. Everyone that I have talked to is pretty impressed with it. It apparently removes the dead pedal along with the power bump. That along would be worth the price. I cant stand hitting the throttle and waiting for it to take off. Banks appears to be spending a great deal of time with the L5P (in part due to their military contract I suspect). I wouldn't be surprised if Banks and GM are not working together behind the scenes, if that is true, I would imagine that the L5P will get a power bump soon and likely follow the work that Banks has done to substantially increase the power of the L5P that they are documenting on You Tube. Like mentioned, Banks spends a lot of time to get their product right.
