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.

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.

Can't wait!

If I get another 100 ponies in this thing, I’m gonna get in trouble.

There is a TSB for rough shifting:

By any chance, does the JB4 tuner have the capability to disable the auto on/off start feature?

you can disable it by hitting button below the shifter

Yeah, they can. But it’s only for the current drive. I think the question is to disable it completely

Sometimes I press the button too quickly and I don't notice it didn't register. But more importantly, I would love to save myself the step of having to press the button every start up. The feature is ridiculously stupid, at least for my drives. A 45 minute commute to work, and maybe my truck turns off 2 times for 4 seconds total.

Ditto, all of that.
Does anyone else’s N light blink going to or shifting through neutral? Mine blinks twice like.. “I’m getting there, one sec”

I haven't noticed. Will look for it next time in the truck.
