The ECU controls max boost through the BPC. Installed as designed, the MBC regulates pressure reaching the wastegate and bypasses the BPC altogether. The dood says he is using the MBC to set boost at 15 psi. Therefore the ECU cannot be affecting Max boost in this configuration.Tweek's Turbos said:No, I'm really sure the ECU still has some controll over it. Isnt a MBC just delaying the signal to the apc from the wastegate or something to that effect.
Either way, the warmer temps have alot to do with it.
