I OWNED A 92 DODGE WITH A COMEALONG IN IT THAT GAVE ME 23 HWY MPG.
I OWNED A 97 DODGE WITH A CUMMINS IN THAT GAVE ME 22 HWY MPG.
NOW I HAVE THIS 98.5 THAT GIVES ME 15 ON A GOOD DAY WIND AT MY BACK
24 VALVE , I HAVE A MISZER CHIP IN, 4 IN EXH. FROM TURBO AND A K&N 410 GEARS
ANY SUGGESTION TO IMPROVE MPG??
2 SPEED

 

get some smaller gears. 410s kill mileage. or go with bigger tires
