| PPE or Quadzilla Stealth 2 will help with mileage compared to stock, but there are alot of things that affect mileage.
Does the guy have a lift and big tires? We had a Dmax in here last month with 37" tires for a Stg IV Suncoast kit, and while we were at it he had us do a gear swap. Swapped the 3.73s for 4.56 and he picked up about 4 mpg.
Does he drive like a racer everywhere? That sure will kill mileage
Tires inflated properly? |
