I have been considering getting a custom tune for my truck. I have been tossing either the Westers or the Predator around. I think I have it narrowed down to the predator.

 

Question I have is will the Predator run good with 87 or 89 octane, or does it require 91/93 octane.

      Not what I said but I can work with it anyway. Complete combustion produces CO2 and H20. When it's cold enough you can 'see' it as water vapor but it is always there and more so the better the tune up. It's physics, not an argument. In a cold motor when the cylinder jacket is below the condensation temperature the water goes to the pan and not the PCV system. Heating the oil moves it from liquid to vapor where it is removed by the PCV system. When and how much depends on temperatures. Of the air, the water and so on. It has little to with the humidity. Water is a combustion product.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      I can only guess as well that something was clicked on that brought you to the half ton choices by accident. By all means try again and chose the 3500 and sort out that its the cab and box configuration you want and choose four wheel drive ( rather obvious to have a transfer case ) and to make sure the dually isn't chosen. I find or at least did a couple of years ago when I was sifting through the options that it would sometimes jump ahead after choosing the series of truck and in this case 3500 and skip some of the other initial configuration choices and have to watch the heading bar and sometimes back up by choosing the first in the series of option break downs. I think sometimes the computer will remember items that were last chosen and skip over the first part. Anyway go through it all and depending on the trim level chosen and I think the LT is one that may fall into that where the option of having the 4 high auto transfer case can be chosen, where as a High Country doesn't show that option as it just comes with the fancier ( not necessarily better though in terms of potential problems ) transfer case but for sure both transfer case choices are equipped with high and low range in the HD truck segment. Like Newdude said who works at a dealership, its the half tons that are the ones that will come with the single speed unless certain options or trim levels are chosen that add the two speed transfer case but as your looking at an HD, you don't have to worry about that hot mess.    One item that at least didn't show up and not sure if it does yet or not in the HD options on the manufactures pubic website is the upfitter in cab switch option if one is desiring that. Unfortunately its not wired in at the factory but the panel with the switches is on the dash but the wiring harness to be installed gets tossed under the rear seat to be installed by whomever after the fact to complete the installation.

      Yesterday we brought home a 6yr  old Havanese dog from a nearby SPCA.  We've had her for 24 hours and we are delighted with how well she is adjusting to her new home.  It  was a huge decision to adopt a dog at this stage in our lives but we believe we made the right choice!   it was reported that her first 6 years were ones of neglect.  I think she's already realizing her life is going to get a whole lot better...  so is ours!

      I thought I was building a HD 3500 srw, maybe I was lost.

      Which 2027 engine will you choose?

      No doubt, I definitely agree with you. However, considering the 6.2 and 3.0 have been catastrophically failing with very little miles, I figured I would put trouble free. I’m at 18,4xx and still not a single issue.
