peak boost is about 18 lbs. @ WOT unloaded, when it shifts at that pressure I get a little squawk (stall I think) from my turbo. basically I have been watching my boost accelerating from stop lights and getting on the freeway. I hope that helps? thanks, ~Aaron

Someone with more experience on the EDGE EVO can chime in, but I think you should be making more peak boost, especially on the higher programs, like 22-24 at least.
It sounds like you probably have a boost leak, indicated by boost being slow to respond and lower than normal peak boost.
What I would do if I were you is, take all the IC boots off and clean and inspect them for cracks. Reinstall them nice and clean and tight.
The most common problem causers are the crappy orange ones under the Y-pipe, which http://dieselpowerproducts
carry replacements for.
You might also want to consider the CCV mod at this time as well.
Doing this should net you some more boost, lower egt's, and better accleration/power.
