Did you change out your cap too? That's where you'll get relief on your system by dropping the pressure.
Do you run some real time software while driving, like Torque Pro on your head unit? Are you getting good temps in all conditions?
Any codes coming back after resetting with a good scanner and not just seeingold codesdue to scanner not being up to it?
