I'm surprised you didn't trigger your overboost switch, my guess is that your boost gauge needs to be rebuilt - mine does the same where the telltale will show max boost (.09 in your case). The on the next boost cycle will drag when the needle comes up again where the telltale shows an overboost. Try to keep an eye on the actual boost needle on your next drive, and be sure your overboost switch is hooked up and in working order.
