After some proper time with JB4 installed I can say it's definitely good. I'm long time JB4 user on previous platforms. It's easily the best piggyback option.
Does anyone know how much lower of a ceiling for fueling the MT base tune has compared to comp tune? I'm only just starting to run some ethanol, and even at E20 there doesn't seem to be much headroom left for fuel trims. I think this aspect is being overlooked when people say you can achieve the same overall results with a JB4 on Base as Comp. Sure, you can turn boost up to same level, but fuel trims are going to max out quicker on the Base.
This may force me to a ECU unlock quicker than I expected, at which point the JB4 will have less appeal...
