    How hot are your EGT's?

    That should be a stout setup.

    There are some pulling rigs out there making passes at 1800*. 1500-1600 is warm, but if that's where it stops climbing I'd say you are running pretty good for a race/play tune. Not sure I'd tow with it..

    I wouldnt worry about 38 psi as long as your timing isnt sky high. I run a bunch of 5.9s at 45 psi on stock head with no issues.

    The basic way to get EGT down is, more boost or less fuel. Tough to play with WOT timing without being on the dyno. Do you know how to do either?

    27 degrees main? At what load/rpm? Are you not running pilot injection? Screen shot?
