Boost adjustment not working as expected

I installed the Diablo tune on my 2005 Dodge Neon SRT-4 and noticed the boost was set way high. Stock boost levels are 15psi and the tune was maxing out my gauge (20psi). I adjusted the boost levels using -3 which I assumed would take the tune down to 17psi. It did reduce boost levels to about 18psi on the gauge. However, when I adjusted boost levels to -4 (thinking it would go to 16-17psi) the gauge is now reading 19-20psi.

Why? What am I missing?

all the stock vacuum lines connected?

Stock vacuum lines are connected and there are no leaks (did boost leak test) and I checked again after the first run of 20psi+ to make sure nothing blew off. Stock tune holds at 15psi solid so problem.

Read out the last tune written and post it here. Have to see what the tools doing.

I guess when I went back to stock it deleted the tune file. How do I get it from the device without reinstalling the tune?

There is no way without reinstalling.
