New project
I have 1/2" ss lines to irates rr return in the valley. It has worked well for well over 200k miles, but I'm sure with the dual pumps, it was way overkill for the injectors I was running. I emailed irate this week about the -200 bosch pump, and I'll probably go that route just to simplify the...- psduser1

New project
I've been told a single will hold pressure reliably to somewhere around 200 cc, but I'd rather err on the side of caution with fuel flow.- psduser1

New project
So, fuel pump recommendations? I've been running dual SD pumps, but I've seen a few guys run aftermarket single pumps with bigger injectors, and id like to simplify a bit. Any thoughts there?- psduser1

New project
The 205 is the hybrid, I assume. I've also ran the 80% nozzle, just to shorten pw a bit, running a nonstock hpop. I know a lot of tuners prefer the smaller nozzle, just for ease of tuning, but, with a manual, there's no Trans issues to manage. How heavy are you loading your dually for...- psduser1

Fwiw, I'd think tuning would manage most of the torque issues that cause problems with low end fueling.- psduser1

New project
I do want some input on this project, tho, since the last time I did this was almost 15 years ago. I've always ran 160-200/80 100 injectors, and liked them for towing. I know low rpm smoke, lots of oil, and so on. I get all the downsides, and I've put roughly 300k miles on two trucks with them...- psduser1

New project
So I bought another project... 01 f350, manual 4x4. 410s, just over 220 on the clock. I've put a few thousand miles on it as a srw truck, and I hate towing with it! Dual wheels are so much nicer. Since I've got two trucks that worked great set at 450 hp, with all the appropriate parts, and...- psduser1

Tuning the 7.3 in current times
I agree. The whole "starting with well used cores" just exaggerated the issue.- psduser1

Tuning the 7.3 in current times
My injectors are all remans from unlimited diesel. They are smoky at cold startup. I think is a combination of higher mileage engines and reman high mileage injectors. I don't really think it's any single builder screwing up the rebuild. More likely the quality of cores is deteriorating as the...- psduser1

Tuning the 7.3 in current times
I've run 160-180/80s for years in tow rigs, and they worked well for me. A lot of guys dislike them, especially at high rpms (race type scenario). I could see that, I guess, but in a more stable application, they worked well. A tight 38r, a good aftermarket hpop, dual fuel, and a zf6, php and...- psduser1

Hard steer question/issue
Caster needs to be adjusted. I've got an excursion does the same thing. These trucks should be set -3* to -5 ish. Bigger tires exaggerate any kind of barely noticeable issue quickly. -

Stumped again
So I tried a different idm as suggested, no change. Checked ohms through all the injector circuits at the idm plug, all were at 3ish. However, I didn't see any power to the idm. I checked with the key on, engine off, obviously. Went back and swapped the idm relays with a couple different...- psduser1

Tuning the 7.3 in current times
Was that on the hydra, or a ts chip? The tunes are the same, method of delivery matters, sometimes, lol. I have one truck with a hydra, the other three are still ts chips, with nothing wrong with them. Other than the wrong tunes for the setup I want to run.- psduser1

I don't know, really. I was just fiddling around to see how the app worked. I'll check it out, but I don't really it's designed to do that much indepth. It did clear the codes.- psduser1

Stumped again
Torque pro thru the obd2 Bluetooth says I have 150-160 rpm, cranking. I still need to find a pinout for the idm to verify power there, just gonna continue to be a side project, I guess.- psduser1

That's the plan. 3k psi at the rail, I'd say long enough, lol.- psduser1
