boost at cruising speeds on a tune?

I just put a 5" exhaust with DPF, CAT and Muffler delete. I reused my tuner from Power Hungry Performance from my F150, they reflashed it with their race tunes. On the 90hp and 140hp tunes at 60 mph I am around 11-12psi of boost. Is this typical for any other types of higher hp tunes? Should I be worried on longer trips?

Thanks!

That seems high. If I am correct I am boosting around 8-9psi at like 80mph

It doesnt seem to be running hotter or any thing but on the 60hp its like 5lbs... I really plan on getting an H&S or Spartan later this just allows me to remove my DPF without codes. I am still a little worried about running those other tunes all the time.
