No boost and no codes?

Timore · 12-31-2012, 06:24 PM

Hey I'm getting only 4psi boost but the car isn't throwing any codes, I tried reflashing the tune but still the same. Anyone experience any problem like this? I have a 2012 335is, mods are in my sig. Thanks

check your fmic connections and the charge pipe.

Check FMIC and BOV area for starters since they are the aftermarket areas of the pressurized system.

It takes a good 4 seconds of Wide Open throttle and underboosting before it throws the 30FF code.

Looks like I blew the charge pipe off the intercooler...

I had a vacuum leak when I had similar issues.
