Default Less power in third after mods?

I just put on a 2.25" pulley, reattached 92 TB after using 94/95 from Floz (I know, I know...), and fashioned a CAI (it'* ugly, but does the job). The car pulls much harder in first and second, but when it shifts to third under hard acelleration, its seems to have less power than it had before, and boost seems to drop a pound or more from pegged above ten to about 8 or 9. Is this to be expected with a smaller SC pulley, or is this a fixable problem?
