Sold my EGT setup (with new probe/leads) 2 weeks ago and the new owners are getting real low EGTs.
They are running 17psi on a stock garrett and also running +20s. Their fuel pressure was at 80psi and saw 1300 egts, and then cut it down 76psi and still 1300 egts. I hope that their base isn't 76psi....
I don't know where their egt probe is placed or if they cut the leads..... but they didn't see any difference in temps. (maybe because it's waay too rich right now?)
Should they be still 55psi base with the +20s... or do they need a tad extra base like they are running to be safe around 1500 at 17psi?
They are wondering if there's an issue with the gauge, but it should be fine.
