I'd expect to see 1400F or less at full throttle. Granted, I'm used to Rotary EGT's, which almost max out normal EGT/Pyrometer gauges under normal use (maybe 1400F at full throttle turbo, 1500F full throttle N/A, all the way up to 1600F idle/cruise N/A)

Are we talking an in manifold or an after turbo sender? There is a big difference.
