Aeroforce - 2 Bar MAP Sensor Question

[StangLoveR]

Question for you folks who are familiar with this setup.

I wired it all up, and punched (as per the instructions) 5.8 slope and -13.2 intercept given that I'm in Houston (sea level). With key on, engine off, it's reading -0.1 to 0.0, so looks like things are setup correctly...just took it for a spin and its reading no more than 7 lbs of boost, when with my pulley I should be making about 10 lbs. Could there be any other adjusting I'd need to do to the gauge, or should the gauge given the parameters above be accurate and the conclusion here be that I have a boost leak?

Thanks!

Whats your setup consist of? My sensor was pretty accurate

I really just need to know if there's any other adjustability, or if instead, given that it's showing "0" at engine off, whatever boost it's showing should be accurate.

Setup is a 2.3L whipple with 3.375" pulley with JLT CAI, no cats, stock cams.

I may not have tightened the NPT/barb fitting into the intake well enough - it's so damn hard to reach in there with the bypass valve and the fuel rails in the way, etc.
