When I got the FMIC upgraded, the JB3 actually caused a boost leak when set to +5 over boost (because the silicon hose popped off the passenger side of the FMIC)... I need to update my sig block because I'm set to only +3 over with no pop off issues...

I may invest in a CP as well, but I don't see any that are compatible with the E70/F10 series... (X5 and 5 series share the same parts)
Too bad Matt isn't around to help you with the mods anymore.
