MSD E-curve Distributor Set Up???

I can get the cap off and on without too much trouble but it is tight. I set the dials to 7 & 1 and hooked up a ported vacuum line to the nipple that is hidden on the bottom side of the distributor and isn't even mentioned in the instructions???? According to my calculations this should give me 20 degrees initial with 15 degrees advance at 2500 and 10 degrees of vacuum advance at 4 lbs vacuum for part throttle driveability. This helped a little with around town driving , but I didn't notice anything at WOT. I'm going to put a timing light back on it and see if advancing the total timing will help.

The tuner has limited experience with the E curve, that's why I'm trying to get the timing sorted out before I take it the chassis dyno.
