Boost issues ... help .

[HussainM5]

Hi everyone
something strange happening with my 2013 M5 F10
current mods :
aem meth kit
cattless DPs
intakes
Bootmod3 + Tune

so with the tune car supposed to run on 22.44 psi but it reads only 18.5 psi ( 16-17 stock ) !!
changed many staff like :
Solenoids
wastgate Actuators
Vacuum line
Spark plugs
Coils
Exhaust flaps actuators control

and still got 18.5 psi !!

anyone experienced something similar?

Any help please..

I guess you need to speak with bootmode3? but,

you cant map boost as such. You ask for a certain amount of torque and the ecu adds boost, timing, fuel and throttle to attain the set torque.

My car is standard in a cold climate at sea level and the most I have seen is 15psi normally I only see 13psi.

you need to find out what torque the tune is requesting. With DP's, Meth and decent intakes it maybe only requires 18.5psi to attain the requested boost. Your car might be performing as it should.

Ask for a tune with max load... maybe that’s the culprit.
