I'll add $.02 more of my cents to this. If this were my motor and it did have some issues when I installed it I have a good enough relationship and trust with my builder that it would be repaired by him without any problem. He would also help me if I needed his help to resove the fuel issues.
I will also add I'm not a wiz at working on a dyno, but I promise you my motor guy can make the dyno results say anything you want it to. + or - 200 hp no problem.
Again jmo, but this thread is beyond getting anything resolved.
