I have been looking for a while at a non-intrusive way to help the lazy throttle response on these trucks.I took a look at the $300 sprint throttle booster but heard horror stories of guys staying without throttle control when they failed.Some research on Youtube and Amazon put me onto the Jet maf sensor so I decided to give it a try since worse case scenario if its snake oil it can just be returned.I took a spirited drive so the current performance of the truck would be fresh on my mind parked the car and installed the sensor then took right off.I intentionally did not disconnect the battery to reset the ecu as to help keep variables the same and avoid a " placebo effect ".To my surprise the installation offered a modest increase in throttle response and some additional wheel spin.The sensor is aesthetically indistinguishable from the factory sensor so I am sure whatever physical alteration is done if any is miniscule but noticeable.The difference feels like the truck either has a bit more timing or a leaner afr so I do not think it would be wise to use one on an already tuned vehicle.The reason I decided to make this post is because when I was researching the topic myself all I could find were people being dismissive with no first hand experience at all.To be clear if warranty is not an issue a tune is going to be %100 the way to go but if you do not plan to tune I think one of these is worth a look.I have tried on my wifes GMC Terrain as well as my Regular Cab 4.3 but here are some guys with modded 6.2 , 5.3 who also seem to like it :

If you get a good tune on stock MAF the throttle isn't lazy any more. If the new MAF has a different response curve than OEM it may help in one area but hurt in another with no way to know for sure other than seat of the pants. And after initial gain the ECU starts to try to adapt to it in closed loop will any gain be nullified? IMO put that $$$ into a good tune that will re calibrate the ECU to get full benefit from your stock control system components.

      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.
