Default 2009 2.5i Turbo Build MAP Sensor question

Well i have been doing some tuning with my tuner from RomRaider and im stumped with this, i got a 2011 sti MAP sensor, and got the scaling in but it wont show boost it hits a peak of -3.2 on the Map sensor relative pressure, i have tryed multiple offsets and multipliers and nothing seems to do it, but i put the stock one back in and i can get boost to show up only thing is it maxes out at 5.66 psi because it wasnt designed for more, unless there is a setting i can change to get it to go over 5.66psi, but its hard to get proper tuning done without the actual pressure in the logs. Any ideas?

possibly a bad MAP sensor? I used a Perrin 4 bar for my SC build and it worked great.

Relative question....could a NA map sensor just be swapped for a Onni 2,3, or 4 bar sensor instead of using a black box to trick the factory sensor?

Did you ever get this sorted out? My OBD scanner pops up with more than 5.66 psi when I get on it. Not 100% sure if that reads from the same sensor or not though. Also, what turbo are you running, and what wastegate solution did you come up with to run lower boost pressure?

No i didnt i just figured out how to get my Innovate SCG-1 boost controller to read data into Romraider and that MAP sensor is more accurate then a stock style MAP anyhow, and i got a Kinugawa adjustable boost actuator, and had them send me a .3 bar spring so my wastegate pressure is like 3 or 4 psi without a BCS
