I had the BMS with JB4 on map 1. I was getting some hesitation in acceleration after installing it, it wasn't all the time but it started to make power unpredictable. After a few months I decided to take it off, never experienced the issue again.
BMS was telling me it was a MAF issue and suggested taking the MAF out. They suggest running it without one and making the JB4 remove the code not running a MAF would cause automatically. I wasn't a fan of that solution so I decided to not reinstall it.
Im running JB4 w/ Chargepipe, FMIC, DP, and exhaust on map 2. I'd say I'm FBO without the intake... I do plan on using a drop in though. If whooshing sounds aren't important to you... I'd say skip it all together, gains from the intake aren't noticeable enough. Also with the gain in hp I've seen in dynos there is also a drop in tq. That said the BMS intake did sound awesome and I completely understand why so many people run it.
