at least I hope it will. If you overlay the 535 with stock manifold and 1420 charts they are identical from 4400-5200 and then the PE kicks it up a notch while the 535 starts to fall off. When comparing to Seb's 535 with and without inconel manifold chart I calculate the PE 1420/inconel manifold to be right between the two 535 charts until 5400 at which point the 535 drops off and the PE should keep going to a peak of 560-570 or so.
