Sup Earl lol, I see anywhere from 20-30psi Ive seen more, but the efficient part of the turbo for more power is between 20-30psi of boost. It definitly can see more without a doubt most Ive gotten was 35psi I believe hard to watch gauges when your rolling at 100mph on the interstate lol.

Just got the CTS reading boost, so now I know what I'm looking at. Boost is maxing out at 22#'s for me with Matt's SRL+ Tune...is that a function of the stock stix? normal?

My opinion yes, if we break it out probably moving less boost because its moving more air at a lower boost now compare to the stock turbo, my idea behind it is that The boost you build on a stock turbo lets say 30psi is moving a certain amount of air, now the powermax boost at a lower boost but moves the same amount of air but at a lower boost. Does that make sense lol things are soo much easier in my head then typing. You can also touch base with Matt about your tuning if want.

I have seen upwards of 30psi ( I am pretty sure I have a leaky uppipe or positive air shut off), I am fairly close to the combo you mentioned.

Seeing 30 PSI if I let it get there. Blew loose the Banks turbo hose yesterday hitting north of 30 PSI so off to the dealership for a OEM replacement hose. I'll be going back to an OEM hot side pipe.
