Hi...

OK, what Mach number will that give me? .60 or .55?

There's no "one size fits all" cruise N1. It all depends on aircraft weight and winds at flight level.

That's what I have found out I want to find a N1 that will give me .77 Mach and ITT of 795

The problem is the engine is going to perform differently based on the altitude you are flying and the temperature of the air. There is no single N1 speed that is going to give you .77 Mach for all of the possible cruise altitudes and temperatures. You are asking for cruise charts that I don't think anyone has.

OK I have found if I run it just under the barber pole I get close to the temps of 795 ITT it's just this plane will easily go past the barber poll red line
