Hesitation under part throttle

On my 2002 wrx if i speed up under part throttle the car seems to pull un-consistantly, from like 2500-5000 rpms or so. It does not hesitate under full throttle, any ideas?

my car (03) started doing that after doing the 3/16th vacuum connecter thingy.

It's in the scoobymods forum under "Improving Factory Boost Solenoid"

But if that's not the case for you, I don't know what it could be.

Car Info: want a WRX

Bad gas? Try resetting the ECU after putting in some good gas if that is the case. Do a search for more information and check out a thread called "What does resetting the ECU really do?"
