It is because of the boost. The MAP sensor is a diagnostic sensor, and it's not designed to see boost. I keep tripping mine, it's keeping me from passing emissions.

I've swapped to two different MAP sensors, and checked the vacuum routing, still the same problem. It's funny, I only threw that code twice in over a year with the supercharger, and now with the turbo, I can't go 50 miles without throwing it.

I think you may can use a check valve maybe. Or something like that

Here is a link, its from an integra, but it should work on a max.

(about half way down after the parts and prices)

It's how you trick the MAP sensor using check valves.
