high egt's

Hi, long time reader, first time poster.
I have a 2000 f350 crew cab 160,000 7.3l auto, 6in sky jacker, 35/12.5x16 tires, 4in straight pipe diamond eye exhaust, S&B cold air intake, hypertech power programmer. This is my first diesel, built a few 289's and 302's but never messed with diesels before. Thanks to the guru's on here I know that my max egt temp when taken at the manifold is 1250. When I am empty and running into hills I am reaching almost 1100 egt This seems ultra high to me. My thoughts are either a injector is out or possibly the exhaust back pressure valve is messing up. Am I on course with these thoughts? and how does a back yard wrench turner check injectors? I have learned that if you pull your valve cover you should see oil squirt out of them, but if the tip is clogged or leaking would you still see the oil squirting? I just want to get this figured out before I do damage to the motor.

Before you go digging around under the valve cover, what tune are you running on the Hypertech? Some of the performance tunes will make the EGT's go up fast. Second, what's your boost and RPM, lugging the motor will make the EGT's go up. Third, check the uppipes for leaks and make sure your filter is clean. If the EBPV is sticking, you should hear a hissing sound, you can disconnect it and wire tie it in open to test it. After that, get a good scanner so you can check codes and perform tests.

I am currently running code #3, tried going back to stock to see if that changed it and it dropped the egt's 100 degree and truck had no power. Boost is normaly around 5psi when egts start climbing, when they hit 1050 or so I kick off the over drive and boost will hit 15.Can't remember the rpm range, will check tomorrow. I just read about unplugging the ebpv so ran out and unplugged it have not had a chance to test it since doing this. Air filter is new, fuel filter new. I will check out the up pipes in the morning, freakin bugs swarmed the flashlight earlier when I unplug the ebpv plus cant do a test run until then anyways. What is a good scanner to get? Thanks for the info.

crawled underneath today, I have a small leak on each of the doughnuts on the up pipes, pencil size line of soot on them. did a test run without the ebpv hooked up and egt's dropped 200 degrees. so now the looming question in my mind is get rid of the ebpv or buy a new sensor

Just put it on a manual switch and use it for a exhaust brake.

is that a pretty simple switch with a 12 volt power wire using the existing plug? It also seemed a few times on the test run (110 miles) as if it might have partially closed a few times. Also noticed a drastic drop off in how fast the egts go down when off the throttle
