intercooler install questions!!!???

so heres the deal...i got an 02 gt with a v-1 vortech that was pullin 10psi. i got the cxracing intercooler for it and put it on...now i was expecting to loose some boost. from what i read i should loost anywhere from 3-5 psi of boost but when i took it out for a ride and its pullin the same amount of boost...well the blower has a 3.6 inch pulley and now i have a 3.25inch pulley commin in the mail...wasnt sure if anyone has ran a 3.25 from the 3.6 and if so what kind of increase in boost am i gonna see...i really dont want the engine to blow...any help is appreciated. thanks ya'll
