Engine/Transmission (1998.5 - 2002) Low Boost, Low Fuel Pressure Help!

[LBARTLETT]

01', Goerend transmission, Fass 150, Juice with Attitude, 180k miles



Just got back to Texas from Kansas with a load of hay, weighed 34k, fass 150 usually runs 15 to 16 and I could never pull it below 12, now it runs 14 to 15 and I pulled it down to 9 on some big hills, used to at times, on big hills get 32lbs of boost, today the max was 24, seemed like possibly my EGT's were a little higher than normal running 1,000 to 1,350 degrees, had the Jucie on #1, #2 and #3 with no real noticeable difference in the above readings



Is my turbo going? Is this an air issue or a fuel issue? where should I start, truck has been running fine, this is my first trip loaded in awhile this heavy,



any help & thoughts would be appreciated, no leaks, engine and transmission temps were fine



thanks in advance!

Check or replace fuel filters. Also insure the air filter is clean. If those are good check for possible air leak, but that is probably not the issue. Also may have gotten some bad fuel unless this was the case all the way home. Just a few ideas to check.

I'll start tomorrow when it has cooled off
