Laggy boost between 10-20psi

[95eclipseSlow]

i have a stock 7 bolt running and evo3 16g, with a greddy profec b spec 2 boost controller. The boost is set to 21psi. when i get into boost i hit 10psi real quick then once i get to about 15psi it seems like it lags for a second to get to 21psi. It just seems like it gets to 10psi quicker then it gets from 10-21-psi i thought it should be about the same. Is there anything i can adjust in the boost controller to fix this problem? any suggestions?? Thanks

Just get a MBC on ebay for like 15 bucks and get rid of the EBC issues. Don't get a bleed style one though.
