k. , it's a tough decision, I know, I went with the #8, and it's the correct call for my truck (see sig. ) and how it's used. I pull a backhoe every few weeks, loaded hay trailers, logs and the occasional heavy load of pipe. With no cat of muff, I could hit 1300 degrees as measured pre turbo if I really worked it hard.
This summer I installed 215hp injectors and they really complimented the #8. I also found that while towing about 7,000lbs. in the Rockys, I could hit 1400 and up if I didn't back out of it quickly when above 7,000'. That's with the fuel cam plate in the stock position and a new stock air filter.
But as Paul Harvey would say, "Now for the rest of the story", Now I know that a 4" exhaust, improved air inlet, and a bigger plate are in order, do I hear a #5 calling, and of course the pump spring kit and 370hp injectors, and a 16cm turbo housing and on and on and on and on.
If you haven't already, guages are the first modification you should make, pyro and boost.
Boming, try it, you'll like it.
