I have a slight problem wondering if anyone else has had this problem yesterday while driving my check engine light came on but only for about 3 minutes is off right now the problem is the car will only make 2lbs of boost the mods include nm pipes,alta intake,access port,cat back,forge bov and helix fmic i checked all vac. lines boost tubes ect. all tight idles fine and no weird noises or leaks car drove great with this setup for months any help would be great thanks...

 

Can't help you unless you scan the ECU for MINI specific fault codes and reply back.
Grab hold of as Bavarian Technic scanner, scan, record, and post up the EXACT fault codes.
