I carry 200 or so people across the country in a few hours. That definitely helps. Figure in the old days they would need at least 2 horses for 4 people. That’s 100 horses for likely a 6 month trip. That’s a ton of horse farts which science has told us is one of the leading causes of ozone degradation.
Good feedback thank you.
I'm sure you know that you will need something to calibrate for the gears if you don't already have something.
I use an “ECRI” for now to make minor changes as well as my larger wheels. I have a lot to learn about “tunes” as I really know next to nothing about them. I know many (all?) require you to send the ECU in to be unlocked. Since I don’t want to lose my daily driver that long, I’ve read they can do it there. I thought about driving to the airport, pulling it and flying out to them and having it unlocked. Curious if I put it back in at the airport If I’d be able to start up and head home. It would make for a long day, but it would be a single day and I wouldn’t lose the truck at all.
Corsa makes amazing products. If I ever do exhaust, that's what it will be.
The swap sounds intriguing. I’m going to also look into if I can get an appointment and do it in house if I go that route. I like the idea of having a second pcm as it’s cheap insurance. With less than 10k miles it would be nice to not immediately have work rejected when they see the unlocked pcm.
I see this is an old thread but have to post. This is not true. Tuning is not done striclty for mileage OR for performance. As a matter of fact usually to get better mileage you will get better performance as well. The "detuning" you get with the factory tuning is to increase reliability but if you are to "tune" it up and increasethe performance and usethat extra power responsibly then you will get the benefit of increased mileage. There is a lot more that goes along with all this but that is the easy read version and the jyst of the point Im trying to make known here.
That’s an interesting take. Have you been involved professionally in the tune settings for new vehicles, or do you have an authoritative source you can cite to substantiate this information?
I can not say I have any proof to provide here to substantiate this fact. Mainly because I'm too lazy or willing to dig that deep in to previous years discussions and follows ups to any individuals involved in my previous tuning. But, I can say this is based on many years of real world experience. I had my 2006 LBZ Duramax tuned by Rob Coddens the record holder of the fastest DMax in the world at the time. He was one of the first companies (ATP) to be hunted down by the EPA or whoever it was that figures better mileage is bad for the environment (ironic, right? I know theres more to it but still). I had a lifted Duramax with the same tires I'm running on the JT right now (different wheels) and got waaaaaaay better mileage. I used to have an excel sheet I made to calculate my mileage over long periods to get real world #'s and trial and error with different tunes and the best mileage was gained from my higher hp street tune. All tunes were "stock safe" with my minor mods but even the mileage tune was barely comparable to the highest hp tune. The problem was if you enjoyed the fun factor at all you would waste the gains in no time. Mileage tune was also much more noticeable over stock in hp levels with snappier throttle response etc. But it is what it is if your smashing the pedal around town all day vs driving reasonably you will get the gains on mpg from more power or not depending. I mean maybe the little gasser responds completely different, I doubt it but I don't know. I do feel these units are under powered too though and still getting used to this thing, it is my first JEEP and I want to give it a fair go with hopes of keeping it for years to come. Got my 06' in 08' and kept it until recently even through multiple other vehicles, so I'm hoping this one suits me as good too.
