Installed my new Edge Insight over the weekend. Had a chance to put a few miles on it today. At 65 mph sustained, with an outside temp of 60, my EGT's were in the 700 degree range, my rail pressure was in the 17,000 psi range, my tranny temp was 165, and my boost, when on level ground was between the 7 and 8 mark.

Are these numbers about right with what you're experiencing?

What are the upper safe limits, so I know what to look for?

 

Keep EGT's below 1200, transmission temp below 190, rail pressure shouldn't go more than 22,000, and boost should go as far as 34 lbs. That's when the waste gate will open.
