Default utec boost controller

does the utec have a manual boost controller? or can you control the boost with the utec? or both? because i just bought the utec, and on the boost controller itself, you can adjust it.

I assume that you are referring the the Auxillary Boost Controller (ABC) that one has to use with the UTEC. It is not an MBC.

The UTEC controlls boost on its own via a boost map, but it requires the ABC to "bleed off" some of the boost in the line that goes to the wastegate. The ABC is usually set at 2-3 turns and the boost is adjusted via the boost map in the UTEC. You have to either adjust the ABC for temperature changes or have a different boost map for different climates. I live in Chicago and adjust the ABC every time the temp changes by 15 or so degrees.

Some have moved to using the GM boost solenoid in place of the stock one. It offers better boost control and you can usually ditch the ABC.

The UTEC does not necessarily require the ABC. The ABC is a fix because the factory boost control solenoid won't flow enough sometimes to build your desired boost. This is a "flaw" with the factory solenoid, not the UTEC, and would be present with any boost controller that relies on the factory solenoid.

+1 for using the GM solenoid. You won't need the ABC with it because it completely blocks the charge air from the wastegate. Pop "gm solenoid diy" into the search.
