I'm not thinking 3:42's are going to turn it into a badass, and I certainly wouldn't come back on here if it were and rub it in anyone's face. It has to improve drive-ability where I drive it most, stoplight to stoplight....it has to, it's freaking math. I also have done a ton of camping and owned mountain property only accessible via steep log roads so towing a small camper up there is not out of the question in the future, or even a boat at some point. The two speed transfer case will be a plus also. Will it be night and day, no, but it will improve. I felt the difference in Dodge from 3:55 to 3:92. Yeah I can tune a 3:08, but I can tune a 3:42 also with better results. It's physics 3:42 is just a better base for everything else than 3:08. I won't do either for right now. Like I said I'm not screwing with my warranty on my brand new expensive for me truck, others who can afford to chance giving up the PT warranty on a brand new truck by having a third party reprogram your shift points and speedo I'm happy for you, and more power to you....really. I have no plan on criticizing you about it either, I just aint going that route at this time for my own reasons. Everyone has an opinion , good for you and live and let live. I know there are a lot of guys on here with 3:08 trucks and I'm not trying to make anyone feel bad about their purchase because I did it myself, but I'm sorry my 3:08 truck is an absolute dog turd from a standing stop. I'm choosing to make it a half a turd instead and keep my warranty. I'm not rich and don't have a friend who is a GM Tech or a brother in law who owns a dealership to help me out if there's an issue. I want my warranty intact. I also want to keep the truck longer than usual because I am almost positive I will not like what's forced upon me in the 2021's.
I think the black 2020 LS Custom should look exactly the same as the 2019 LS Custom Midnight Edition I own right now after the swap except I'm having the PPV air deflector put on since the manual says they will remove the bumper cover to swap out grilles. It's a few minutes for them at that point and the dealer says no problem, we'll do it while we are right there, A freebie, except for the part of course. I have another deflector I cut down that I was going to put on myself but this looks better IMO.
I appreciate all the feedback including that some think it's not worth doing what I'm doing. Rest assured though I have no intention of bragging about how badass the results of the switch are, or anything else, that's not my thing. I enjoy the forum and I appreciate the good answers I have recently received on other threads, very helpful. Thanks again and carry on.
