Stock 7.3 2001 dually w/ 300,000+miles. Can I add peformance without hurting motor?

[Clownboy88]

Hey guys! I have a 2001 F-350 crew cab dually with a 7.3 and a fresh rebuilt tranny. The truck and motor have 309,000 miles on it and the tranny has less than 500 miles on it. My questions and concerns are, can I add any performance to this truck? It's all stock. I just wanted to add a air intake, 4 inch turbo back exhaust, and a chip. Would that be ok? Please let me know. Thanks.

You should be fine. Iv heard of a few 300,000 plus motors blowing the heads off because of boost. But they were running stage 2 injectors and a big turbo, you should be fine just drive it with common sense

Yes. I got more than that but barely.
I'd get gauges of course before the chip.
Then an intake or exhaust. I did a DIY intake with a Baldwin filter. And a Walker Big Truck Muffler on the exhaust.
Then get a custom tuned chip.

ya i'd see no issues doing that. the biggest thing at that mileage is the trans but if thats a fresh rebuild id say you're good. deffinately like mentioned above gauges before a chip

I've got that many miles on a stock trans save a Factory Tech valve body.

thanks for the info guys. so what should i do first? put the air intake and muffler on first and then add the chip or put the chip on first and then put the air intake on and muffler? and what gauges should i get? just the turbo psi one or is there another i should have besides that one? thanks again

Most get Boost, Exhaust Gas Temp and Transmission Temp if the have an automatic.

I'd say get the exhaust and intake before a chip. My thinking is that some tunes will raise EGTs and the exhaust will help lower this.

Get all of before a chip. The gauges are the most expensive thing and they need to be done before a chip so might as well spend another 100 or so and do the rest.
