Default 2000 International 4700 with orion

Well, this is going to be a bit different to show my initial experience with the Orion system as I sadly was not there to experience it being put on my truck.

That being said I have been patiently waiting for it's debut. But for what ever reason on June first I called to see if there was any new news on the unit. By the stars aligning they said today was the first day it was officially for sale. No convincing was needed by them, "Just take my money".

My brother was home and able to install it both from reading the clearly written directions and hearing my brother's feedback everything was straight forward and to the point. The turn around for the tunes were pretty much next day.

There were 7 power options available to me on the tune which you have to use the flashing unit to install and only one can be used at a time. So no on the fly switching. But that's fine with me.

175hp
195hp
210hp
230hp
250hp
275hp
300hp

My truck is as stated in the title is a
2000 4700, t444e, 5 speed spicer with two speed rear end. All of which to my knowledge have 227k miles on it (Except obvious fluid changes and one rear end servo) with both welders on board and two gang boxes full the truck weight is just over 18k. (Today It was ran with just one welder and gang boxes empty so probably just over or under 17k)

Some minor things on the truck.
Factory down pipe to a 5" Donaldson straight through muffler to a 4" stack on side of truck.

A freshly rebuilt turbo. <- it's going to be getting a wastegate 1.0 housing. EDIT: I went with a KC300X stage 1 .83 housing.

Oil rail crossover.

Stainless bellowed uppipes.

Pyrometer and boost gauges.

Brand new water pump, radiator, and hoses

EDIT: photos not scaling.

Once I return from work later this year I'm hoping to go over the valve train, new single shot injectors, glow plugs, and finishing the regulated return.

Here is a short video sent to me of the truck with the 275hp tune. I had my brother back it down to the 250hp tune due to both the miles on the motor and wanting to limit the boost to below 30psi. During the end of which you can hear my father's laugher of joy as well. I can't promise any other videos for awhile as well. So for that I'm sorry as well.
