rpd boost gauge

['09SS]

what is the cutoff on the topend of this gauge? i just installed the gm tune with the 3 bar map sensors. and then put term's tune on top of it my boost is going right to 25.5 psi and holding that till it tapers off from the turbo running out of steam. i lowered the dals to 250 and it is still doing that. is 25.5psi the max the rpd will read? and is my actual boost pressure is higher than that?

I believe 25.5 is the max RPD, yes. Get a manual boost gauge. And add the boost pid voltage to your scanner, go from that for now. Be careful with the stage kit dal's, its super easy to go over 30psi. I actually had to bring mine down from stock.

You can log upto 30psi from those 3bar maps, just have to make a custom pid with a recent beta scanner.
