Mine is doing the same thing, I just did a 21 psi run, and datalogged it, it said 18psi at the highest.
John, what information did you need me to PM you? Just my address, and email address? My phone started breaking up, sorry about that.
18.5 Or so is the highest the stock map can read, so if you guys are running 21-22 psi and wondering why it says lower it is because the stock map is maxxed. If you have stage 2 or 3 you can go to 28 or some odd psi without maxxing the map sensor. Check the difference cruzing or in light boost and see if it is still lower.

I can send you datalogs with the FTM, and with Innovate's Logworks of the same runs, spiking 16, holding 14, but the FTM shows a good 3lbs lower. The stock MAP sensor should be able to read that accuratly, that's just over the stock boost the car ran. I just upped mine to spike 18, but without water injection, I can only get about 10.5:1.
