Boost controllers

would the manual boost controller actually help build up higher boost levels at lower rpm and different throttle positions to keep traction and help the torque

Woah woah woah…be careful with statements like this. Boost controllers can not make a turbo system generate more boost at any specific rpm range if it’s not physically possible. A systems ability to build boost is mechanically limited by a number of different factors including, but not limited to, the size of the motor, volume of air, size of turbo, etc.

So, boost controllers can not help you build boost if it is not physically possible for your motor and turbo configuration to do so. What boost controllers do is help you maximize what is mechanically possible.

@Nate_Drake

just thought id throw this in here… some advice from zilvia

"Are you running a manual boost controller? Your torque is higher at redline than it is at 5000 RPM, which would probably be untrue if you were at constant boost.

It just looks like a MBC setup dyno where the boost tapers up to full boost.

IF so, you really should get an EBC, you are missing out a ton!"

I am running an AVC-R…dunno how the Profec works, but I can’t imagine using a boost controller that DOESN’T have RPM specific duty.

People running a MBC are forced to dial it in so it hits some “peak” boost. Consequently, they spool up suffers dramatically.

EBC allows you to achieve the fastest possible spoolup without overboost and then hold it there.

Yeah, those comments are generally accurate. Good on them for recognizing your lack of boost control from your trq curve. Don’t often see that on web forums.
