Stay out of the kitchen if you cant take the heat! :lol88:

Between two EJWA's, and my Comp, they have all performed very well, and NOT too hot. Heat is fuel burning, more fuel is more heat.

[QUOTE=RAWilliams;756409]150hp increase from the Smarty alone? That would be one heck of a custom tune.

there are some massive ones out there but are so aggresive you can only use them pulling or racing and you will get codes for over fueling with them just like the adr 4k. i wouldnt use them i would just stack, im just stating what i know can be done with it if you have the money to spend on the custom tuning.

I second that statement. Improved my MPG quite a bit.

I bought a used 2008 2500 with the 6.7. It came with a exhaust delete and a Smarty tuner. The truck runs great but pours out the BLACK smoke. The Smarty I got has a poorly writen instruction book that was hard to understand. I contacted Smarty and asked about tuning to get rid of the smoke. I was told that the exhaust delete was not legal in a lot of places for on road use. Period end of Help.? How about (If you are tuning for off road use do ----) instead of nothing Still love the smoky truck but.
