How much Boost Do You See?

On average daily driving I'm seeing 17psi with a 89 5 star tune. Get on it and 22psi is very doable. Can't quote a number, but I'd swear that I've seen more. Tow/haul is way less.
Realize these numbers are still not that high. I spun the needle off the boost gauge on my Cummins truck. That gauge read to 35psi and I guessed that I was seeing 42 before the needle would hit the stop.
