What do you all think about the Super Chips programmer?
I had one on my Duramax and it was a great unit.
I just switched to the 5.9 Cummins with a 6 speed to try to get better mileage but found the power is not what I am used to with the LBZ Duramax.

go with the Smarty or BDTD. Smarty is more fun though, it has so many options you can play with!

I tried the cortex for a couple days and had lots of timing rattle. Mines a 03 so I'm sure that has something to do with it. I just got a smarty, and the the options are amazing. I also like the predator, never had any problems with it.
