X 2 only two things can cause high EGTs that I know of and thats low boost
and too much fuel. Hopefully Monday will sort things out.
Whats stopping you from adding a few extra Lbs of boost, for a slight increase
in performance.???

Thats nearly right John High EGTs is caused by fuel burning in your exhaust so if you change your cam profile to lift your exhaust valves too early the fuel haven't had time to burn in the cylinders yet and you will get hig EGTs read the link in post #15 the section on Comparing Cam spec might make you understand better

Ok, an update on the situation. Mechanic who did the rebuild pulled the valve cover today and was checking everything out - tappets, lifters, etc. Turns out he didn't like something he saw and is putting back in the standard lifters with the shims. Tomorrow is a holiday here in Russia, so he promised it to have it ready by Wednesday. Hopefully this will solve the problem and I'll reinstall my boost controller and be riding good for a while.

Ok final update on this situation (I hope). I got it back from the mechanic late Thursday and he told me that a couple of the hydraulic lifters had collapsed and weren't holding up, so he put the standard lifters with shims and adjusted everything to the proper clearances.
It was a noticeable difference right away. Now I know the 2.8L is no powerhouse engine, but it seems a little snappier on acceleration and a bit smoother. It took the big hill without a hitch - climbed most of the way in 5th and only had to downshift to 4th because of a slow truck in front of me. EGTs climbed to 500C while in 5th and promptly dropped to about 400-450C in 4th. Note, this was without the boost controller installed, so that's a huge improvement from what it was doing.
I installed the boost controller after leaving the shop but haven't had a chance yet to take the hill with it installed. A big thanks to Stropp, Kimbo, TD and the others for the input. Should have it sorted out. Now it's time to start doing all the optional upgrades I've been wanting to do since day 1

You've been throwing a fair bit of money lately at your Patrol.
Now get out there and take some pics so we can see what minus 30

Well, when the Patrol is your only vehicle, you've gotta do what you gotta do to keep it on the road. I was hoping not to have to do all of this when I bought it last July, but when you buy on the used car market over here, you never know what you are getting, no matter how carefully you check it over.
The two consoling factors are: 1) it cost way less over here than it would have if I had done something similar back in the States, and 2) I now know exactly what I have with my vehicle and it should be solid for many years to come .
