Anyone tried to use stock MAP sensor with Vortech kit on 9psi?

It seems like my tuner has a problem using the 3 bar omni MAP sensor. Here is their response:

"he was having some issues that may have been related to software, but we’re still not sure. We were swapping the MAP sensor back and forth to try and help find the issue and when it finally started working as it should, we had the stock MAP sensor on. So he did finish tuning it with the stock MAP and you should not need the 3-bar. However, you may want to keep it in case you want to go to a smaller pulley for more boost later – then it would be a requirement."

I have contacted Vortech and they told me that the complete kit come with 2.5 bar map sensor and the tuner kit does not come with any map sensor. So I think when the tuner said "stock MAP", he meant the one originally on my car not the one come with the kit.

I have emailed the tuner but have not get any feedback yet. So I assume that they might run less boost than 9psi in order to complete the tune right? As a result I might get lower number on dyno.

Or is it safe to run 9psi on stock MAP sensor? The tuner shop is kinda reputable in my area. So I think they should be correct. They said the stock MAP sensor was not maxed out

But I doubt that the stock MAP sensor will the a good and reliable choice. And everyone including Vortech do not think the stock MAP sensor will be ok.

Anyone has any idea?

Updated:

I got feedback from the tuner and they told me that the person who tuned the car will not be in the shop until next Monday. The car was set to be 9psi but he was not sure. Dyno result is 265/200. with Stock MAP that originally on my car.

I contact Vortech technical department and they strongly suggest me not to use the factory MAP sensor. I think there might be a reason why Vortech's complete kit come with a 2.5 bar map sensor and why they strongly recommend me not to run stock one. Also, I am not able to find any evidence about a 9 psi Vortech FR-S/BRZ with stock MAP sensor.

I dont know who is correct.
