@Dieselfuture How has mpg been with the 285/75/17?

I have an extra I’ll sell. 5$ is shipping.

Thanks Mike for covering that for me!

Yep anytime. I personally have the Fass Tiranium 150 and I think it’s kind of noisy. I would go with the Airdog complete system. You won’t regret it.

I recommend gettin rid of that K&N those are known to foul up these trucks. Go with a BHAF filter. @Mopar1973Man can tell you more about that.

Yup there’s your problem. You need 18 22 psi at idle and 14 16 wide open throttle. I would get a Fass or Airdo fuel system as the stock on will just keep going out. It will be a surprise if you didn’t ruin your Vp44 yet. Replace lift pump and then see wht happens.

A video of what your exhaust sounds like! Lol glad you like it!

If your injectors are original I would just replace them anyway. They can be had from DAP for under 350$.

Right on have you check d fuel pressure? If not I suggest parking the truck until it has checked out.

Sounds like low fuel pressure to me which is going to lead to a new VP44 which will cost you a cool 1200$ or more. Maybhve already killed ur pump. Did you scan for codes with a obd tool or just assumed there was no codes becuase of no cel? OT: @Hawkez seen u have a FTE resonated? Thinking about installing one to reduce highway cabin noise. How do you like ours? Could I get an exhaust sound clip?

The 2010 t style steering upgrade I have heard is pretty good. Blue top steering gears is a vendor here and has many good reviews. Personally I haven’t used either one becuase I have never done front end work. Here’s a link. http://www.bluetopsteering.com/apps/webstore/products/show/7304079 Looks like they’re out of stock but you can send yours in for them to rebuild.

How do you like ur xzt?

So I maybe selling the 24 and buying a 12 valve Cummins in the near future. What is the best year of the 12 valve? Any other tips or advice also appreciated

Just what I’m lookin for. 2k @ 70

https://spicerparts.com/calculators I may be wrong but I calculated by entering the new gear ratio hat the tires would make. I entered 3:69 for the R&P ratio and 34 inches for tire height (calculated at tire size website) and 70 mph for speed limit.

According to spicers calculator I would be at 2035 average rpms at 70 mph.

The main reason I want bigger tires is lower rpm which means more mpg right? I’m thinking 3:69 is going to be the cats meow. I can obtain that ratio with the 285/75/17.

3:69 is what the calculator says. Maybe I should go with the 285/70/17 that would be a 3:81 ratio.

Are u running any tuning? So I ran a grading calculator and I’m coming up with 3:66 for my final ratio. That’s pretty darn close to 3:55 so hopefully it will help with mpg and rpm!

Thanks! I see you have an auto so I bet I could get even better!

Having a Allison tranny is going to change a lot of things.

I can’t seem to make the lookup tool work on my iPhone not sure what’s up with that?

Is there anyone here that can chime in about 4:10s and tire size? Seems like everyone has 3:55s. I am getting 18.5 mpg with 4:10s and 265/70/17 right now and would like to get 20. For 4:10s do I want to go bigger to bring the gear ratio down or not?

Does the Fass I have bypass that return line or no?

Do you have a part number or link?
