What are you considering "high mileage"? A 7.3 isn't considered broken in until around 120k.

Back to your question. Any "mods" you can do to the 7.3 will only help what you've already got. One caveat would be that you will have to monitor some of the mods to insure that you aren't pushing it past it's limitations. That is why you will hear that one of the first recommendations is a good set of gauges to monitor EGT,transmission temp, and boost.

 

Yea it wouldn't bother me as long as I know everything is in good running order. But just so you know if your truck has any weaknesses from high milage - performance mods will help you find them - like a tranny on it's last legs. Like Touchof grey said - get yourself an intake, exhaust, and some gauges before you do any fueling (chip or tuner) and you should be set to go!!

(Thank God for a wife that likes big trucks.)

I've got 195000 miles on my truck, and I'm putting bigger injectors in next week. Don't let miles bother you.

 

Quad my tongue is hanging out which injectors you getting? Phuuleeezze keep us posted.

 

Seen my neighbor while ago and he said he just rolled 480,000 on his 99.5 SD today on the way home. He runs the older SCMT 2 program for about the last 300000 miles on the highest setting with a straight pipe, and now a kwik filter (thanx to me).He even pulls a 20 ft plumbing trailer everyday also, no gauges either.Never done anything to it other than regular maintence. Looks rough, but he drives 90 miles to work and 90 miles back everyday. I guess regular maint and no tellin how long they will run..

 

I've got some Stage I's ordered from Bean, and they will be shipped to me this week. I'll post the results, and my impressions once I get them installed, and wipe the silly grin off my face.

 

Hey quad... are you still running the stock trans w/ those new injectors?

 

Yea,what he said, and are you keeping the PS2K on it with the injectors???
I am still looking for another one, since the first never showed up.

I'm still running the same tranny that came in the truck when I bought it, but since it's still holding up after having propane installed for so long, I'm not sure it's "stock". The previous owner might have beefed it some while he had it.

I've been told that I won't need the propane any more once the injectors are in, but the Norwegian in me makes me want to prove it to myself before removing/selling my system. I'll let you know if/when I decide to sell it.

Because of my schedule for the next few weeks, I've told Bean to send his next available set of injectors to the next person on the list, since I won't have time to install them until the weekend of the 30th anyway. I'll report how the "transplant" went, and how the truck runs after that.

 

Yes, I want to hear about it too.

 

awesome, we will all be waiting.... ohh so patiently.

Yes but hurry please

Why the Bean injectors over say Swamps

 

Both Ryan Bean and Jonathan Ryan are great people to deal with, and either decision would have been a good one, but I decided on Bean's Stage I's for two reasons, they're slightly larger at 160cc's, compared to the Swamp Babies at 150cc's; and they're also slightly cheaper, by $100.
Y'all are going to have to be patient now. Because of my hectic schedule, I won't be able to install the new injectors until the 30th, so I've told Bean to send the next set to someone else on the waiting list, and send me a set in time for my installation on the 30th. It'll be a few more weeks before I have any news for you, but I'll report as soon as they're in, and I've got the silly grin off my face.
