Re: map sensor + boost?

The map sensor itself is will accurately report upto 15 odd psi. The ECU however has no concept of boost. You can run about 6 psi with the stock ecu if you push enough fuel in and it will manage, but even still you are better off getting an aftermarket ECU and tuning it properly.
