Our dyno only reads high when in comparison with a SuperFlow but even then the numbers with be within 5-10hp. It reads lower than what most DynoJets produce as the other dyno on location was a DynoJet. JJ your truck was very impressive and I was also kind of worried about the rod bending factor with the LLY rods lol. I've seen them bend at 550hp before. Very good run and a very sharp truck indeed.
