I am guessing the stock vortec valve springs are letting the valves float. Lack of valve control may also be why a Ramjet crate engine falls off so quickly at higher rpm. The little dip at 4,800 in the curve is something in the tune that I cannot find. In that area the dynamic air suddenly jumps about 10-15 gm/sec above the MAF and the duty cycle jumps up about 5-6% and it runs rich for a split second. I tried lowering the VE table about 5% in that area but nothing changed.
