Arrow 20 PSI with stg 2?

So my setup is 42's, 3" pulley, Injen CAI, Magnaflow catback, Vibrant header/dp (catless). My boost gauge is pegging out while in WOT? I've been wanting to get tuned for a while by a local tuner but he is worried about the way my car is behaving? Is there anything we should know before he tunes or is it just because of the tune?

btw I've got an intense tune? not the it helped much...

any help would be appreciated!

are you using the stock gauge because it could have gone bad
get a mechanical gauge and let us know if it says you are boosting the same

so what you are sayin, is that he can see from HPtuner if the gauge is broken?

Yeah. Get a log from HPtuners and make sure you get a log of the MAP kpa. That will tell whether you are actually boosting that high or not.

If you are catless and you actually are overboosting, then there is something else causing a restriction. Time to pull the valve cover off and check to make sure that there is no valve train damage.

Do as ^ says. That's the easiest way to find out.
