Putting the Factory Turbo IDI to the test!!!!

I finally got to do some pulling today with my '94 IDI factory turbo since all the up-grading I have done. I hauled two loads of pipe each wieghing over 20,000lbs so a total truck,trailer, and load of 35,000 plus lbs. . It pulled it great!!!!!!! Never saw my EGT's above 775 dergrees. I was not on any fast roads so I never got over 65mph but it picked up speed good, and un-tracked the loads on some rough steep places better than my 6.4 by far!!! I am not sure that my 6.4 can pull any better than this old 7.3 with almost 290,000 miles!! Best $2500 I ever spent!

Yea it is on the down pipe and I know I need to add 200 degrees to it to be accurate, I guess I am still under 1000 degrees pushing it as hard as it will go. Am I right on needing to add 200 degrees Derrick? Out of all the diesels I have had this is my first pyro, so I am not too savvy with them. My friend told me to just go ahead and put it in the down pipe, because if the probe burns off it goes straight into the turbo! If I am off on anything please let me know! Thanks.

Hey Howard,
I am thinking it might need some more fuel too, Egt's are low enough I may still have some room! How's your truck doing?

Doin' great. I am going to turn mine up some more when I get the time. It doesn't smoke hardly at all and my EGT's are 250-300 at 65 mph. I can't get them over 325 even at 100 mph and 10 1/2 lbs of boost. (It is cold here-20 degrees)
Thanks for the tips BTW.
Still have the growling noise when the hubs are locked or in 4 WD. Replaced the u-joints to the transfer case, one was bad but the noise is still bad. I think it might be in the front diff
