i am the new owner of a 2004 ford f250 4 door 4x4,- 6.o powerstroke..looking for info & advise to get better fuel economy,and maybe a lil more power..and so far have talked to 2 kinds of owners, 1 that has 200.000 mi & done nothing to the truck,and loves it..- another that says he,s afraid to drive his truck, because every time the check engine light comes on it costs $1500 to fix.! and how everything about this truck is over the top expensive.! myself, I worked as a mechanic,on police cars.-out of high school,and into hot rods..before I worked as a machinist for the last 30+ years.and do all my own work,-since I cant seem to find ANYONE. that can just do a job right. the first time. so I. end up doing it myself anyways.

 

Welcome to the forum

Doin it yerself seems to be a cheaper alternative on diesels anyway.

Post up some pix of ur new rig!

 

ya. I end up havin to go back & fix what they miss,& dont have a lot of money to throw away,& wonder if the job got done correctly, - I work as a machinist. I got the f250 for $16.000 @ 4% rate with 115 k mi.& needed a full size for some time,my 99 ranger has over 310.000 mi & runs great.! - I went thru the motor at 240 k mi.& did the front end,& clutch,but its a step side,extended cab 4x4 & doesn't haul much.. I hope the f250 is near as good a truck as the ranger has been,Id just like to get better mileage,and stay legal

 

What does staying legal have to do with anything?

 

staying legal.? well 1. the e.p.a. has us in a trick bag situation.. they have not enforced many of the new laws.. yet but,enforcement is at their discretion.. so the law applies to who THEY. want it to..like a few I know, who have been hit with outrageous fines for riding trick harleys,that do not exactly comply with emissions, after they passed. 2. if you do ever go to sell a vehicle, the value is ruined, if. you have chopped up, or removed any. emissions equipment.. in fact. it is illegal. to sell a vehicle. if. you have altered it..and you. can. be held responsible.. that is why. I. keep doing all. the trick stuff,on my older rides. that do not have to comply..

 

I was semi kidding, in Hi they don't crack down like CA but they could as well I'm sure. I plan to keep the stock exhaust when I do get a turbo back in the event I need it for a safety check but EPA is almost non-exsistant here. So I was meaning it as a joke mostly. Programmer and ur pretty set from what I've been learning... My buddy told me a good programmer and injectors will make a good bit of difference. Said exhaust is big enough and intake flows decent as well? So they can basically be left stock anyway?

 

 

ya. I been hearing soo. many different opinions,ranging from, just go to hacking off the exhaust.& delete the e.g.r., to be careful not. to go over stage 2 on boost, because the head bolts will. give & blow head gaskets,- requiring the cab to be pulled..to do major motor work..being that I just got this truck,and want to learn how to make it last as long as I am on the hook. to keep paying for it.. my last truck - I still own & use. as a daily driver. that I ordered built the way I needed it.is a 99 ranger ext cab 4x4. after paying it off.- $26.000 over 4 years runs great. at 310.000 mi
