i have 97 F-250 with 351 was told could get edge programmer for it wondering if anyone has used one on this engine. or any other kind of programmers and how it worked i liked edge so was kind of leaning toward that programmer. how much hp and tq do these engines have.
You need a totally different style tuner for the older EEC4 computer in this truck, there are no handheld tuners that will allow timing and fuel adjustments. To get performance with this engine you have to do it old skool and get your hands dirty, it will require a high flow exhaust and valvetrain upgrades like 1.7 roller rockers.
Your 97 is most likely an OBD-2, 5.8, mass air SEFI. In this case there are many flash programmers that will work. You can pull your ECU and look at the tag on its connector; it should note what OBD version it is.
There are 2 ways to find out besides that. 1) look for the diagnostic port, if it's under the dash and is 16pins it's EEC5(OBD2), if it's under the hood and is 6pins it's EEC4(OBD1). 2) Count the pins on the computer connector in the engine bay, 60pins is EEC4, 102pins is EEC5. http://www.fordfuelinjection.com/

That was F150 and 5.0 only though, the F250 and heavier vehicles with the old pushrod motors never got EEC5.
Look, there was/is a government mandate in place that states all vehicles sold in the US, after JAN 1, 1996, be OBD-2 compliant. Count the pins if you want or pull the ECU and look at the tag.

I agree 99%, you just seem to have missed 1 small detail, this regulation applies to light duty vehicles under 8500GVWR only. The EPA classes vehicles over 8500GVWR as heavy duty and did not require OBD2 compliance until the 1998 model year.
And there are F-250's, from 96 & 97 that are still under that rating, the F-250LD (4.9L or 5.8L) which had a GVWR of 8200lbs. Are they OBD-2 compliant, I dunno...but those versions were sold through 99.
I'm not familiar with the vehicle in question, but it's better to be sure than to speculate, unless F-250 beast knows what version he has; LD or HD. Otherwise, just look at the harness or check the tag on the ECU, it wont cost him anything and he'll know for sure.
Honestly, there really isn't a huge benefit with aftermarket tuning on a bone stock speed density application. You can even install quite a few bolt-ons and simply adjust the base timing and install an adjustable fuel pressure regulator.
If you have an automatic transmission, there are plenty of changes that can be made where aftermarket tuning would be beneficial. There's almost as many tuning options for an electronic transmission as there is for the engine.
