High EGTs

I have a 93 7.3 NA I put new injectors in and a pyrometer, Now i found out that my EGT is up to 1100-1200 just cruising at 75 MPH, the pump was turned up and now have since turned it down to help the problem with no change, just no more smoke, this has a new filter, open exhaust, e4od trans 4:10 gears, any ideas would be great

I'm not 100% sure, but I don't think that's too high considering you have a NA with 4:10 gears at 75mph. Putting a water injection system on it might help. If you really want to lower EGT's put a turbo and a intercooler on it.

Did you put bigger injectors in or just stock replacements?

Thats definately high! Where did you install the pyro? What brand and maybe you got a bad one? What RPM are you running at that speed? What size tires?

my dad's 94.5 powerstroke has 4:10's, 265x75x16 tires with a 5 speed and at 60 he turns 2,200 rpm's. at 75 id guesstimate he is turning about 2,800 rpm's more or less. thats alot of revs for a 7.3 diesel cruisin down the highway. my 95 has 3:55's with 315 tires and a 5 speed at 60 mph my revs are about 1,700 rpms and my pyro says about 400 m/l. just throwin in my 2 cents
