Okay so recently installed motorsport 100hp injectors a 10mm stroker pump and airdog 150 and cant keep egt in check love how it runs now but.hate.letting out the throttle. I have a 63mm cheetah turbo.and pushing 38# but im having to hold it back due to not having headstuds installed yet I know that turbo has allot left in it and the tune I have now at wot it's smoke till at full boost and it cleans right up maybe a slight haze that's it

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?

After 2800 rpm full throttle I am running a pilot but it shutsoff after 2600rpm and no post
