Engine/Transmission (1994 - 1998) Over boosting, high EGT's

[DIESELNV]

I think my truck may be over boosting. It seems normal around town, but 50 on up the boost is at 20 psi and above. Even with light throttle holding a steady speed. Climbing a long hill really makes the EGT's climb fast. I put the 370's in last fall, but only noticed this problem recently. Could my wastegate not be opening? I need any suggestions on what to look at.

hmm don't know here. . sounds like you may need to slide the plate back. . did this start during the nice weather we had two days ago? It only hit 70F, but that may explain it. How hot did your EGT get? I will be at Rip Rook's place on monday. If you are not that busy, stop by and we can play with it.

No, it does it even on very cold days. Thats what has me so stumped. I would like to stop by, but never know what time I'll be off work.
