Fork in the road
I was originally planning on a 180/0 build but have been seeing other builds with 238/80 and begining to change my mind. I saw kc turbos YouTube video showing 238/80's and a stage 2 turbo with the lower AR pulling a trailer in overdrive at 1100 egt.
So I guess the big question is what are the down sides to the 238 hybrids, hard start, could starts, reliability, are they typically to hot, etc?
I wanna make this my forever truck and build it right the first time. Buy once cry once.

205s seem to be a good compromise with good power without much trouble of them running hot or being smoky like a 238 can be. It is all about balance. More fuel means it needs more air and finding parts that work well with each other is the trick. Heck I think Aaron is running 250/100s in his but he has a big hair dryer to feed them and the mods to support it.
you gotta decide what you want to do with the truck then build it to meet that mission.

I think you guys know I went around and around and around between the 160/30 or the 205/30. The 205/30 will midrange harder apparently as I remember as can dump the fuel with that nozzle in that area (1800-2800 or whatever) and since my dually is a tow pig pointless to go yuge
With the stock tune they act like 90/30 as I recall at full tilt...honestly drives great! Many pages of data to read until your eyes bleed, do it and research. Think. Smoke one. Eat a sandwich
Agree 100%, decide what you want and need the truck to do and go from there. No better advice given.

Thanks guys, this is all great advice. Perhaps if anyone has some good threads to tag on 205/30 build's.
Honestly I don't know what this truck is going to turn out like or how the family will like it, hopefully this becomes the long haul RV pulling, with the occasional ripper at the stop lights.

Might be some there. Sticks in the mind the 205/30 can unload all 205cc mid range as the pulse width can do it with the amount of time the piston sits at TDC. Something along those lines. One the RPM passes a certain point simply not enough time to unload all the fuel with the 30% nozzle
Currently rocking them on a stock tune and they act like 90/30s on a max effort tune due to the stock injection time from research. I have that Hydra I finally found, need to get that extension cable for it and try it.
Definitely do the supporting mods before injectors. Those really made mine run better!
