Real quick question here, I was wondering if there was a way to determine what boost you were running without having to make a fourth gear pull on the freeway. What I would like to know is if let's say I go to the track and have my boost set at what I know to be 15 pounds, and want to run some race gas and 20 pounds. How I would I know I am at 20 pounds without cranking up the MBC and making pass after pass somewhere else just to see? Now I know I should have probably just set it to 20 before I got there and not laid into the way there, but that is not the point. I just want to know if you can make boost adjustments on the fly without buying some big old expensive electronic boost controller or dual stage(I would like to buy a dual but kind of like mine now) controller.

Thanks in advance.

Just try playing with how much boost you add vs. how much your turning the knob on the MBC... if it goes up two psi with half a turn then 4psi is a whole turn.... etc.

Thers no real way of knowing unless you drive it... plus theres creep issues and the like so theres no true way until you drive it.

Matt, there really isn't a surefire way of knowing. You can approximate that one turn of the boost controller is one pound of boost, but that isn't always the case...

Cool, I figured so. I will probably end up caving and buying a dual MBC. I can hook it up to that Power/Economy switch that isn't doing anything on my center console. Hee Hee :banana:

There you go, give that button a new meaning!

:lol:

Put the gas in before you reach the track or put it in at the track and then leave and go test out on a highway.
