I played with the 120 tune the other day after I installed my prosport gauges. My boost gauge started flashing red at around 23lbs of boost and my EGT maxed out around 1300. I really love these gauges. They save peak readings, blink red and beep to warn you. Below is a link to a video of my gauges with the oil preasure warning, which is set to go off at around 20 PSI.
