No real gains in MPG, pre or post JB4 tuner install....though I am GETTING better mileage post JB4 install. I think it's coincidental to no more winter fuel (which lowers the octane) and the return of "better" performing summer fuel. Just returned from a 600 mile trip down to NY an back.......20.8MPG on the road, 75MPH, no load, two passengers in the truck. But I am running Shell nitro 93 octane.....at $3.89/gal. Can spin the tires all day long in tune MAP #1. Easy install.....very good technical support from Burger Motorsports.I just like power. I don't know anything about MPG gains -- don't really care. That was Riding Deacon in an earlier post about him getting good mileage after the JB4 tune in post #2078. I don't know what it was before. You would have to clarify with him for clarification.
