high mileage 7.3 mods

[Dunne]

i have a 99 7.3 with 359k and still runs good just not the same power it once had. are there any little mods that will not push it to hard just put a little more life back in it? and i am new to the diesel world but herd of some of the mods like foil delete on here.. what does that help?

foil delete is for looks only

[Dunne]

ok thanks. yea it did look better in the pics. ok i just didnt know if it help with temps or anything. are there any tricks to get more out of it? would a straight pipe give more power due to air flow without risking damage to engine?

I just did an amsoil engine flush on mine and it quieted it down a lot not sure about performance but it idles smoother and seems to run smoother.

idk what mods you have but letting it breath better will not hurt it, I would say do the DIY intake and 4 in exh or cut out the muff.

[Dunne]

yea i was thinkin to cut out the muffler. the only thing that i have done is i put warn hubs in it. which was fun to play with since i was told it couldnt be done on a DRW. some guys on dieselstop.com gave me pointers on that one, but it takes forever to get any response on there if you get one at all. other than that it is stock. what is the DIY intake? a part or customizing the air box? i have herd of some mod about drilling holes in the air box or something but i dont know enough about it to try it.

the DIY intake is a 6637 filter from NAPA and id cut the muffler/cat off or do a full exhaust.

[Dunne]

ok thank you. i just found that filter. i will have to try and pick one up this weekend. i noticed that it is round vs my square one. do just remove the air box? and i will probably have to cut the muff/cat and weld in straight pipe myself right now. i cant spend alot right now with another kid due in a couple months so i am tryin to stay pocket friendly. thank ya'll for the input. i will try to get the exhaust work done wthin the next couple weeks and the filter this week and get back with an update to see how it works. so if someone could verify that the filter i am talkin about will work.. replacing square with cylinder?

[Dunne]

also was wondering for future reasons, is there a difference between straight pipe and stacks as far as performance goes or is it just for the visual? hoping to start building the truck next year. reuild the 7.3 and start really gettin more out of it, just in the mean time i am takin baby steps to make it last me till after the new kid and things get stable again. once again thanks
