Does any one know if w4m supports the 06 models yet? I recently bought a 06 sierra 5.3 ccsb z71 w/ 3.42's and it seems to be a dog. If so what percentage TM would you suggest on doing, I plan on keeping this truck for a good while and dont want to ruin the tranny. I do towing a 16' w/ 4 wheelers time to time, but that is about it.

thanks
Kenny

 

As far as I know yes he does but you would have to contact him for sure. For the TM I wouldn't pull much more then 25%
