upgrades and fuel mileage
 

i have a stock 6.7 thimking of mbrp exhaust s&b air and bully dog tuner what kind of fuel mileage gain should I see

The bully dog is worthless except for the extra gauges and there is no point in doing an exhaust unless u do it from turbo back and that means u need a tuner that lets u delete yer dpf. Thats just my opinion!

bully dog is good for making a trash bag heavier...........full exhaust and good tuner

If your truck is a 07.5-09 I can set u up with EFI Live if its a 2010+ then we have plenty of Smartys

Better to go turbo back with the exhaust. And after this stuff is done you should see a decent increase in fuel mileage.
