I have a '93 ford F250 460 4x4. It's had quite a bit of work done. It has less than 10k on a remanufactured 460 with stage 1 cam, and heavier valve springs. I put a banks power pack - so a banks cold air high flow air intake tubes and filter, headers, and full 3 inch banks exhaust with no cat- as well as a BBK duel 61mm throttle body and 1 inch spacer.
I need to upgrade my ignition system, but msd is in the works.
Engine backed with ZF-5 trans and a dana 80 1 ton single wheel axle off a f-350 with limited slip in the rear end. Has front leveling/overload springs rebuilt steering and 5k air bag helpers/overload springs in the back. Front is still the IFS dana 50 unfortunately. But I rebuilt it's compnants too, until I can put a solid axle swap.

What I need help with is my fuel and programming on the engine. For all the extras it doesn't feel like I'm getting all I can from it.
I was wondering about jet programmer/chip?
Also it still has stock old injectors and stock fuel regulator. Should I put a few more pound injectors in with a adjustable fuel regulator? Or just new stock lbs. Injectors?
It has way more lag than I would hope and it has been running a little rough. Any help is great. Thanks.

There is a really good article in I believe 4wheeler or 4x4 magazine.It covers all the upgrades and tuning done one at a time and results.Its worth reading.How do you like the banks exhaust?I went with heddman and a straight thru muffler.Tail pipe is slightly modified from a diesel suburban with mandrel bent 3”.Banks is supposed to be the way to go though.

I have an '88 F250 460 that the EFI was just an issue. All new parts and it still fought me. I just slapped a Carb and HEI on it and called it a day. I can control everything. So, I would go complete aftermarket with your Fuel Injection so that you have control! I just wanted cheap and it cost me $140 to put a carb on my truck.

What is your operational altitude?
Cam specs?

The EFI engines as a rule run lean at WOT. This is compounded when you increase engine efficiency.

Running an aeromotive adjustable FPR is helpful. If you are near sea level 26# accel injectors are helpful.

Though this is a patch of sorts it works.

If your in tank fuel pumps are OEM this can be a problem as well. They are 33 gph.

Running a few additional degrees of ignition timing set at idle with the spout disconnected is helpful as well.

Are you still running the factory speed density setup? I struggled through the same things on my 97 w 460 and speed density. what I've done is pickyback on a MPFI setup using an A9P computer (manual trans), adjustable FP regulator set at 38 psi, along with opening the exhaust. This keeps all of the other things in the truck working, which was important to me. The injectors are 24lb stock so I don't think that you are starving for fuel. I got my MPFI setup from mass-air.com, they are pretty good about getting you up and running and that alone made a huge difference in my performance, it went from dropping power at 3000 rpm to actually making power above 3000 and not just noise. My next step is to install the TWEECER setup so I can adjust spark and fuel tables since my setup now is currently using the stock 302 fuel and spark tables in the computer. I called several places, like Bama tunes and they don't have a chip for the 460 so the only other option is to find a dyno shop that will program something that old or take your chances with a 302 chip. Good luck, I haven't found any shops like that yet...

Your going to be lean lean

you will be lean lean. Then you'll lift a head gasket.a random back fire once in a while. These trucks where lean with all the air restrictions stock. Better check the air fuel ratio. For now un plug the o2 sensor. Keep it in open looop.

I am planning on running 26lbs accel injectors and a very hot msd ignition. What pumps would you recomend? I agree my stock pumps aren't doing well enough.
I travel in elevation between 4800ft where I live to 6000ft then to 10,000ft. What do you suggest?

I have had no backfires. I have been running it this way for 6 years now. she needs a tune up but I've had no real issues other than I wish I had a gear doubler.

At your elevation the 24# injectors are fine.
I believe the ECM is using the high altitude timing and fueling tables at your operational altitude.

We are direct with high flow fuel and use the 255 lph pumps with our crate EFI engines.
Headers and free flowing single exhaust. Banks authorized dealer here.

What if anything have you done so far?

Did you add initial timing? 14 to 15 is fine.
