MP X-ram for Hemi, whats the deal?

Hey, I think I fixed it! Took it out last night to a biker bar with about 50 harleys sitting around and all the riders on the deck bullshiting when I pulled in. I've got big tube hedders with 4" exhaust and dynamax race mufflers and needless to say, the car was louder then most of the harleys and gave them all something else cool to look at. Anyhow, back to the car. I put 74 mains in, screwed the air/fuel screws out 3 1/2 turns and set timeing to 38 total. The surge is 99% gone and car runs like a raped ape, I would say a hundred more H.P. then my old in-line set up. Well ,it seem like alot more power anyhow.
