What heads do they use with the stage 4 builds? CNC Compressors?

From the get go I asked my dealer for performance performance performance. I decided between the street legal, warrantee stays stage 4 kit, part #92500011... And I stayed with the race ready kit from what I saw on the net and it was recommended from my dealer knowing my ride style. My numbers were good and I'm happy with them, 112hp, 114 tq. Nothing at all to complain about but do have questions. My bike Dynoed with no miles on the bike. My riding buddy, who has 6500 miles on his 2012 FLHX SG 103, decided for the street legal stage 4 kit and chose V&H power crossover duals. Sweet set up, he loves his, I love mine. What I don't understand is that his Dyno pulled 114hp , 112 tq as compared to my race ready kit w/high flow injectors. My Dyno sheet given to me was uncorrected, and his Dyno sheet was corrected . I understand that the numbers for the exact same set ups on 10 occasions will give 10 different readings...humidity, weather, etc. 2 weeks later and with 1000 miles, and along with my 1 k service I'm asking them to redyno and see what else can be gotten. I am getting some decel popping, a backfire here or there and a ping at 2500-3000 rpms when rolling on the throttle in 4th and sefinitly 5th and 6th. I'm getting 30-31 mpg and my friend is getting 37-38mpg. I dont care about fuel economy, and just mentioning for this comaprison. Of course if I would have known I could give up 2tq and gain 7-8mpg, save $400 and keep my warrantee, I certainly would have liked to have the choice. That's an expensive 2 foot pounds, lol. I was looking to get and squeeze whatever I could, I was more and still am always looking for solid torque number, the HP isn't a concern for me once over 100hp. Do our techys here think a broken in engine yields higher numbers, 6500 miles vs 0, and that's why my numbers were not at the top of what the kits advertises. Did my high flow fuel injectors only cost me 7-8 mpg and nothing else. New Dyno is next Saturday and I'm curious if I'll have any gains , or loss for that matter . The bike does pull great and numbers are only numbers, but when the bikes were done just about back to back, you can't help but compare the different stage 4 kits dyno numbers, with all things being close to equal and our numbers being a close flip flop, 112, 114 vs 114, 112... As to why and if my next Dyno may be better or even worse ( they'll save the first map) . Ill post after next Saturdays service and dyno. Any thoughts guys ? Thanks for any input. Dean

I talked to Scotty today and it was running 107/107. He's going to try a little more fine tuning and perhaps a lil timing. I'll post the final numbers and dyno sheet when she's done.
