Tuning
Yep, Im going with these guys as well---soon as someone puts up a dyno sheet for the reg 3.5EB, great thing about the JB4 is that you can take it off in a few minutes and there are Zero trace of a tune, because there is no overwriting of the ECM. You change the map profiles (each with diff Boost PSI) by their data cable and a software program you load onto your computer OR buy their BT and download the APP and you can get lots of other info plus change the Maps on the fly through the APP and update the JB4 as well when needed.
My guess is that their tune on the Raptor 3.5 was a very conservative tune, but the 2.7 tune is much more representative of what is possible.

Well, he didn't say stock, he said normal, and assuming we read and interpret what was actually typed, and assume that he is not purchasing a tuner and keeping the stock file (are you seriously saying that?)...... the answer to that is you can maintain the stock tune, just not the stock file (since you want to split hairs) and tune sport mode. Either way, it's possible. He mentioned nothing about keeping the stock file. So incorrect all around, sorry.(well, not sorry)
I had virtually exactly what he is referring to at 2 different times while tuning my truck. An altered SCT base file, and the original mild normal mode tune used for logging.
Again, you can retain the stock tune if you wish in normal and alter the sport (and tow / haul) tune for that matter, there would be no point, better to do a milder shift tune in normal, and an aggressive one in sport. Heck you can even separate out 4x4 parameters in all mode too,
Not everything in life needs to be a pissing match, sometimes people err. Good grief. Petulance is abundant around folks with massive ego's.
I have a JB4 in my Infinity Q50 red sport, which I absolutely love, so thought I’d drop one in my new 2018 F150 and it’s just as awesome. It’s like a completely different truck. If you’re looking for big gains without flash tune and possible warranty issues, this is the way to go. I also have the Bluetooth adapters in both vehicles so I can log data and change maps on the fly. You guys will love this plug and play system. Install was super easy too.
