boost problem ...

whats up guys I have a little problem here. I got a pale of 110 octane and after filling up, did a switch map over to a savvy map that mike @ gst made for me.
it was GREAT for about a day or so, then all of the sudden my car didn't boost past 15lbs
the tune was set for 22lbs and its never had a problem hitting it, even with 91 it was hitting about 20lbs. (on the 91 map gst made for me)
Im back on 91 octane, the base map is the 91 octane map (20lbs of boost tuned for ) and my car's hesitating at 15lbs. it holds 15 fine, but wont go more..
anyone have any idea whats wrong?

thanks for the reply
i checked all the pipes and they seem to be fine. I believe all the boost lines were fine aswell.
i'll take some pics and maybe it'll be obvious.
thanks again

Alright guys, it seems that the ecu was just a little flustered. After a quick reset everythings fine again, so it was just a software confusion.
wooo that takes a load off my shoulders!
thx for whoever recommended the ecu reset <=]
