Injection Pump calibration question

Hey again all! Is there a major difference in calibration between IPs for N/A and Turbo motors?

So I inherited this truck from my late grandfather about a year ago. Had some serious upkeep to get it running. Was running decently and then started running really rough and barely starting and blowing tons of white (not sweet smelling) smoke.

I replaced the IP with one I got from autozone about a week ago and it cleared everything up for the most part.

Last few days I'm starting to notice (Idk if it was like this and just with the drastic change I just didn't notice until now) still just a small bit of white smoke (still not sweet) on idle and a bit more on throttle like pulling out onto the road. It idles at low rpms and sounds like maybe, just maybe a small miss every now and again when I listen to the exhaust.

I was needing to replace the injectors and was recomended R&D IDI Performance - Home and out of curiousity for price comparison I went to his IP section and noticed he sells 2 separate calibrations for pumps. One for turbo and one for without.

Did I mess up terribly by just getting the pump that was available to me? If its not that big of a deal should I just try new injectors? I couldn't replace them when I did the pump because if I put any more money from that paycheck into the truck my wife would've been unpleasant to be around I'll try to get a video of it when its not raining to let y'all hear it and see what I'm talking about. As always thanks for any input!
Chris

Oh and I took it to the store today to get some groceries and it still drives fine. Seemed like it had power (though I'm still new to it and nothing to compare it to) and can even do highway speeds at 70 mph.

I let it warm up real good and it didn't change the low idle. But when I came out of the store and started it up, when it hadn't really had that long to cool down, and it had a much better idle and sounded way better. Didn't check the exhaust cause it was raining.

So when i start it warm it was fine. But letting it warm up from an initial start has no change.

No difference in pumps as far as I know.. Usually if the IP teeth are off by even one it's a pretty rough idle as far as I've experienced. Have you drained the water/changed the fuel water separator filter recently?

If you are getting white smoke, advance the timing. Simple.
Advance the timing by rotating the entire pump towards the passenger side. The alignment marks on top are "rough guess" marks that will get the engine running, but have no bearing on final timing. Just advance it till it starts really clattering and losing power, then retard it slightly.

Autozone pumps(and most cheap vendors) are a total crapshoot; some work, some don't. You have intermittant errors, oddness due to them basically just cleaning and theoretically testing worn pumps.

i would talk to the the manager at the store and see if they will refund a fuel part that's been installed ..

say it's having intermittent issues and just not working well .. and that you don't want an exchange .. just a refund .. since it's only been a week they might do it .. though with a pump it may be one of those things they won't refund ..

i would think autozone and orilies would be probably be very low quality rebuilds .. essentially just cleaned and gaskets and tune probably ..

if they would refund it .. i would take it back .. and get one from R&D ..

AutoZone was all I knew. Didn't figure out about R&D until today. I have a lifetime warranty on it. So if I continue with problems I might do that.
