The truck will shift at 3250 anyhow. The extra RPM is for sled pullers.
I need to test the latest PPE tune. I've seen it in action, and it runs pretty hard.
As far as the boost controller goes, the PPE is the only adjustable boost controller for the LLY. If you change tunes or need to experiment, it's the way to go. You will see a big gain running 29-32 PSI. Casper and Blue are set at 32. Err... Well Blue still is!
