Default Boost logging maxed at 18.43?

I have been doing some logging in my car and it is saying the car is topping out at 18.43 psi uncorrected. 04 STI ECU is what I am using. Does anyone know if this is it? I thought I was good at least till 22 psi. Any input is appreciated.

What parameter are you logging?
Use "Manifold Relative Pressure (direct)"

I used corrected today and it logged what I believed it to be(a tick over 20 psi). I will try the direct thing though.

On the 04 sti ecu the right peram to log is manifold relative pressure 4 bit.

the 4 byte is working great. What is the advantage of the 4-byte logging?

More precision from the 4 byte logging.

I always use Manifold relative pressure from my car and it peaks at 18.43 psi... should I try logging with a different manifold pressure parameter and see ?

You should always use either the (direct) or (4byte) parameter

if the 2-byte version is available for your ECU, I would use that instead of the 4-byte. It also has no effective limit for turbo models.
