I thought the same thing based on the VQ35DE, but I was surprised at the way the runners were setup on the VQ37VHR manifold. I am sure the airflow is equalized at some point, and the fact your AFR's were that close indicates that is the case.

Most people use the HPX MAF sensors (this is what UpRev recommends/sells).

Anyway, good luck. I am sure you will get it sorted out. You obviously have some good people supporting you, and these are pretty minor bumps in the road for a custom setup.
