i got a '12 Ralliart and i wanted to bypass the solenoid to run a MBC to up the boost a little for more of a straight pull. i have figured out how to unhook it but everytime i hook up the MBC it maxes at 15lbs and it wont go any higher. i was wondering if anyone had a write up on how to re route all of the lines to where it would raise the boost. i have had some knowledge of turbos but wanted a little more on this

thanks.

Either change the OEM pill to a GST or UR one and tune, or get a 3 port and tune. I have not heard of much success with a MBC, and given that you would need to tune either way why would you use one over an EBC or better pill

well i heard through the grape vine that it was a little easier to squeeze out a few extra lbs to where it wouldnt affect anything. the tune shop here said that of the factory map and all that you could run up to 20 with out any problems. but with having the EBC it will not let you. i have seen a way on other cars, but they dont have as many vacuum lines as the RA's do so that is the part i got lost on, i saw on another thread that someone did it but it was an older thread. ( https://www.evolutionm.net/forums/ev...t-solenoid.htm ) so i didnt want to bring up an old thread, not knowing if things changed from 09 to 12.
