Old Acro, et. al.:
1) John's series on "Those Fire breathing Turbos" was aimed at the TNs.
2) I made a late-night error in my post to you earlier. Your TC Target TIT should be in the 1350-1400dF range. Lower CR gives higher EGT/TIT values. That should bring your numbers closer.
Please accept my apologies for the error. Brain fart late at night.
