I suspect the split BLM issue is due to the difference in distance fuel needs to travel between left and right rails. Typically we see D/S bank as leaner than P/S. I would plug the fuel line directly to the back of each fuel rail and then to the regulator. When i had my Xfire, one of the mods was to re-route the fuel from "in-series" to parallel plumbing for each TB. I once measured a .5psi drop in fuel pressure between the TBs with the fuel line in series. That FP drop was enough to make Chevrolet specify different size injectors for front and rear TBs. The front TB used a 62# @10.5psi while the rear used a 65#@10.5psi to make up for the differential FP. However, parallel plumbing made the engine run sooo much smoother.
