Hello Is anyone running Smarty on a 99-02 2500 or 3500 with 6 spd and 4.10 gears? How does it perform?

 

I have a 01.5 HO. I hooked up the Smarty a couple weeks and is running unbelievable! Anyway I have run in in fuel mode and level 7. Finding mileage is up on 7 more then the fuel saver. Lot more fun to drive. I have a 32 fifth wheel that I used this weekend and put it on 5. No lack of power. Would not trade it for anything, makes the truck feel totally different. Dealing with Bob Wagner is also a pleasure

 

6 speed and 3.55 here and the main thing I like about the smarty is widening the usable powerband. I find myself driving in 4th more rather than stepping to 5th around town cuz ya don't have to worry about hitting 2700.

Besides that smarty makes the turbo want to spin and the truck want to move
