I have a 2011 Mini Cooper s and the car ran great. Only light on was because of the O2 sensor (I have a catless downpipe) then I got a stage 2 tune from RPM and now it idles rough and when I put it in sport mode is goes into limp mode and throws a code (P325F). Also still have the P420 code from the O2 sensor which the tune was supposed to turn off. Anyone have any input on what’s happening? Idk if it’s just a bad tune that needs fixed or something mechanical. Thank you for any help

 

What spark plugs are you running? and whats your fuel rail pressure at idle?

 

mom running NGK closer plugs for the tune and I haven’t checked my fuel rail pressure yet but I’ll be doing that today
