Hey guys I gotta 08 dodge cummins fully deleted with the mini maxx. Wondering where u get the best mileage? What setting? And also what are u getting for mileage? I got 283500 on mine. Computer says 16 mpg. I'm gonna hand calculate my next few tanks

 

Hey tntmechanic
I have a 2012 cummins with an H & S mini maxx i drive alot through town and i usally atand around 14 to 15 mpg on highway i usally get around 18 i have an aftermarket fuel system by airdogg and im about to be getting my truck straight piped with "5 exhaust straight back from turbo ill let you know how that helps my milage

 

So you're fully deleted to? What do U run your power level at. I was on tow. Turned it to performance to see if that helps

 

I would just get a 4" and save the money for other mods, but i know 5" is the in thing.
Unless a truck is pushing 600hp or more there won't be any more gains 4" verses 5".

 

My truck is pushing around 725 horse and yes its fully deleted i keep mine at performance setting 24/7 and it does help with milage as long as your not hot rodding it everywere your good to go and im getting the 5" because i like the deeper tone it has then the 4" everyone has the own personal prefrence but i just decided to go with the 5" only diffrence in cash is 80 bucks

 

I alos forgot to mention i have a dual disc clutch by Ky Clutch and a airdogg aftermarket fuel system and a AFE Performance cold air intake and i have studed my motor to handle the extra boost and hp my new fleece turbo will be throwing

 

725 hp is a lot got any dyno sheets? it must be making 1000 ftlbs torque.

 

No i havent been able to hook the truck up to dyno yet unfortunately but from the new turbo and everything ive put on it should be making close to that which im not saying my truck makes a definite 725 im just saying it should be in the ball park around that but I would really like to find out and gook it up to dyno which i hopefully will be able to do sometime soon

 

That's a very respectable number for a daily driver the 6.7 is a awesome engine!

 

U fellas no anything about low boost fuel settings for the 07.5 to 09?
