Did it boost ok before the tunes were installed. Maybe dropping back to stock just to check it out might be a good place to start. Have you scanned for codes and do you have any gauges? Any recent work done?

I bet its been losing power over time its probably hard to tell

check and clean MAP,EBP sensors and tubes

I bet you will notice a Gain in power when the issue gets resolved

any gauges
