Question Questions

I am fairly new to the diesel market, so I have a few questons / comments.

I have a 2001 F350 4x4 crew cab 7.3L with 170,000 miles.
It has a 4" turbo back MBRP exhaust, AFE stage 2 intake, and Edge Juice with Attitude monitor.

I tow a 34ft 5th wheel which weighs around 14,000lbs.

To say I have been dissapointed with my upgrades is probably an understatement. Specifically, my egt's are super high, no matter what setting the juice is set at. I will be at 700-900 degrees city driving on the freeway even at the stock setting. When I tow, I can only muster 45-50 mph @ 1275 degrees on a 6% grade. I have never gotten over 16lbs of boost.
None of my upgrades improved mpg or egt's whatsoever, and I only noticed minor power improvements.

Am I expecting too much? Are my egt's normal? What kind of boost should I be getting? Other than an aftermarket turbo or bigger intercooler, how can I lower my egt's?

Any help would be much appreciated.

Scott

Sounds like you might have a boost leak somewhere. I have custom tunes and I told my tuner about the EGT's being high and he fixed it for me. If it were my truck I would start checking all the intercooler boots to make sure they are tight and not leaking. I would also get rid of the Edge and get some custom tunes on a flip chip.

Thanks for the reply.
So where would I go to get custom tunes, and how much does it cost?
What is normal boost for a 7.3L?
