honestly man, JB4 is nothing but problems. It should help throttle lag (low RPM) but I'm not certain. my vote is to go with an ECU tune, it will be much more reliable then the JB4 and will solve your throttle lag issue.
its ECU tune > JB4 > throttle remaps like sprint booster. the tune would be much more effective with minimizing throttle lag then throttle remaps while bringing in real power gains.
very nice F10 buddy. I got a 2011 RWD N52 equipped 528i also in titanium silver and I love it.
good luck
