Setting it with the car off and pump on makes no sense to me. Set it with the car running and warmed up, pull the vacuum line and turn the reg with the allen key to the psi you want. Setting it w/o the vacuum is setting it for wot cause there is no vacuum at wot. It will drop when you put the vacuum line back on and thats normal.
mysweetlx, try 35psi with your combo and tune from there. You'll probably need less psi, but the dyno or track will tell you.
