Max E Tork
 

Crankin Up The Power On Your 6.5 Turbo Diesel | WickedMag

So I read this article and it mentioned putting the Heath turbomaster on and the 80 hp Max E Tork. Anyways, they lost mileage after only installing the turbomaster, from what I've heard its normal. But, when they put the 80 hp Max E Tork on with the turbomaster, the mileage went back up to what they were getting. So I was wondering how many y'all actually have the Max E Tork 40 hp or 80 hp, and what kind of mileage gains/drops you have received from them.

Thanks
