A mild "heavy tow" tune from one of the reputable Duramax EFI live tuners will do wonders. Don't believe all the naysayers who say it will just ruin your truck. Simply not true... If you want to inquire more head over to the Duramax forum.

Never even heard of a black bear tune?? But EFI or other reputable tuners can get u the power of the new trucks for pretty cheap.
Just know how to use it.
Go over to the Diesel forums and you will find that about 90% of the engine and transmission problems are on trucks with tunes.
I have a 2005 Dmax and have never been short of power for normal towing at posted speed limits.
The 2007 has more power than the 2005 and also the 6 speed.
I would trade for a classic 2007 at the drop of a hat and be happy with the stock configuration.
