wondering if there is any power chips that would go on to a 1989 f-250 7.3 liter and all if any fab required  

I dont believe there are any chips for those years however you can turn the fuel pump up.  

thanks i will try that  

Pre 94s do not have a CPU the are mechanicly run. As stated above you can turn up the injector pump and get a little more out of her. If the truck is runing a turbo and you have some time you can turn up the boost some too. You will need a pyro and a boost guage to turn up both.  

Supposedly the pre-Power Stroke 7.3s had a really restrictive turbo housing. You might want to look at upgrading that, too.  

does this appyl to 94 turbo diesels idi motor, and why wont a turbo off a 97  work on a 94 if listed by part number are the same, i have a an almost power stroke mine was made by march 94  almost the last idi motors.  

im also looking for things to do to my 92 f250 with a non turbo 7.3 that has been bored to and 8.3 but what size exhaust is best and does anyone make a complete air filter set up for it?  

No offense, but trying to get power out of a non-turbocharged diesel really isn't worth it, IMHO. All you're going to get is a heavy, smoky fuel-hog. I would look into putting an aftermarket turbo on it. You'll get more power and better mileage. If you're going to spend the time on boring it out, etc, you'd be just as well off putting some lower-compression pistons in it and bolting on a turbo.  

i know i should do a trubo im just not at that point yet but size exhaust do you reccomend.  

right now i have dual 2.5's and its got that popping sound and its real loud. i do get pretty good mpg's though about 16 in the city and 20 on the highway.  

and you would get better with a turbo.  

2.5 is really restrictive, get a turbo for it and a 3inch down pipe then stright pipe it with 4inch and get a 5inch tip.  

if you got the room to spare in your wallet banks makes a real good turbo set up for that truck. my dad put it on a 90 idi 7.3 and it was night and day how much difference it made. and you wanna talk about something that would roll smoke.you put that truck in second gear and dump the clutch the smoke was comin lol.
