The first tank of fuel verdict is in with the 60 HP tune, 23 degrees timing and 1850 bar psi! The evic showed 18.6 and handl calculated MPG was 17.44 (not bad for a 4x4 3500 drw with 3.73). 453 miles and used 26 gallons of fuel. My numbers are a little bit skewed because my truck spends a good bit of time idling. This tank was spent about 50% city, and 50% highway driving and a little bit of it light towing (two jets skis to the lake and put them in and took them out of the water). I am trying to talk my self in to trying to 150 tune to see if fuel mileage is better but I am worried that i will be like Ratlin' and want to use all that extra power that is there! I have a hard time not hot rodding my truck with the 60 tune! It runs so well now! Please hold together for me 68RFE! LOL
