101 question.

a boost controller just changes boost levels. as boost levels changed though, don't other parameter needs to be adjusted also to be safe? question more or less is what are the dangers of solely adding a boost controller?

I had nothing but issues with it on my f10. Drivetrain warning, false boot pressure faults, etc. car drives better without it lol

Our DMEs are designed to adjust parameters automatically. It can compensate for varying air temperatures, fuel quality, etc. That being said, it can only adjust so much. By adding a boost controller, you're eating into that safety net.

Say for example fuel can adjust +/- 10. By increasing boost, it's running at +3 all the time. Not necessarily something that will cause an issue, but now you can only go an additional +7 before it can cause issues. Hope that makes sense.

the dinantronics sport plugs into 2 sensors. Does the ECU then make changes to fueling and timing to maintain stock AFRs?

Yes, the ECU adjusts automatically. The issue is that the adjustments aren't always instant and the more boost you add, the more drive-ability issues you have. Sometimes it works perfect, other times you floor it and it feels like there is no boost for 2 seconds then all of a sudden all the boost comes on. The trans also shifts slower at high boost levels.
