Currently running 7lbs boost. MEFI 4B WITH MSD Ingenious software. Mock engine on the Dyno was 925 HP. I don't seem to have this. Engines run great until boost, then seem to struggle with RPM. I'm thinking that the boost compensation in the fuel map is to rich. Just don't want to go to lean and have detonation. Do you think the Crane 651 cam would be to much and inhibit reversion?

are you tuning with wideband o2s? You should be able to see if it's running rich in boost and adjust the fuel tables accordingly
