Hey All,

Have a question and I'm not sure how to proceed forward.

Back in 2019 or 2020, I took my car into a shop to get the muffler noise selector deleted, suspension, and new full exhaust and tuned. The car runs great and no issues to report. The only item I did notice with a odb2 scanner that they set the throttle at 30% on all modes (tour, sport, and track) when I start pressing the pedal. Again, no issues to report at all. I am very happy with the way it is running and performs.

I now have a job that is over thirty miles from my home. What I would like to do is get a tuner to (if possible, save the existing tune), and put tune on that would help with gas mileage.

Alternatively, if possible. I'd like to set the throttle 0% for Tour mode, and keep it at 30%, for Sport and Track. If there is a specific tuner than can achieve this, that would be huge in knowing what to purchase.

Any help would be greatly appreciated. Thank you!

Just drive it and enjoy it. You will not get any kind of mileage gain that will offset the cost of a tune, so it will just be a waste of money. I used to commute 270 miles a day. Even with a few bolt-ons and a tune to match it gets 21mpg. You can't do much better than that with 500hp

Changing the table that sets that "30%" isn't going to increase fuel economy, it's just going to adjust how fast or slow you get there. Variable cam timing and how soon the engine gets into performance enrichment are a couple things that could have been adjusted and could affect fuel economy but it's hard to say. To answer your question, buy hptuners mpvi 3, buy the credits and license the vehicle. You can pull the current tune off of it and then try to make changes at your own risk or pay someone to change it. It's anybody's guess how it's currently tuned though and if there would be anything to be had by changing it.

Thanks for this info, after jlaudio posted I may just forget the idea. A credit to write a tune every time is kinda crazy. $50 bucks to test after spending $400 is wild.

Appreciate the insight on this. Are all tuners like this? $50 bucks a credit to write a tune to the car seems kinda wild to me. Any other tuners come to mind that you would recommend?

The license is tied to the device that tunes the vehicle. You paid for this when you originally had it tuned. A new device tuning it will require new license. It isn’t every time a tune is written just the access to do so. The only way to avoid this is to take it back to the first shop that tuned it and ask them to change it. KingLT1, megahurtz and Ted Jannetty are the main turners on here that could help you out. I’ve started doing it as a side deal but don’t have the experience they do.

Oh so officially I'll need one credit/license to tune the car myself, with unlimited writes for changes. That's not terrible then!

Well, it's 4 credits to tune the ECM, because you have a 2017+, and 1 extra credit if you want to go into the fuel system control module as well. However, it's a one-off cost indeed, these are lifetime credits, you can retune the car any number of times afterwards.

The change you want it easy, but the problem is that the cost to tune your car will be more than you will save in fuel costs over the first 3-4 years.

I would agree - very little to gain from a retune. Drive like there is egg under foot, pump up the tires, reduce your speed...far more impactful to mileage.

I commute about 40miles one way everyday and my 1LE gets around 27mpg just cruising in 6th gear. Just take her easy on the acceleration.

Just to be clear:


$400 for the device
$250 ($50 x5) for the credits


$650 total to have unlimited tunes on that ONE vehicle.




How does a remote tune work with this set up?


If I go to a shop to have it tuned, can they utilize my device and then no cost for that part of the tune cost? Just their time and dyno time?


I'm a newby and just getting into the learning phase.

With that setup you can hire a remote tuner that edits your file and you use your credits to flash the car.

If you go to a dyno shop, they will usually have the option to pay them for credits and they use their HPTuners to tune and flash the car. Or most will use your interface to flash the car if you already have credits. The benefit of owning HPTuners is so that you can datalog your car and whoever you pay to tune your car, you own the file and can edit the file for any reason in the future. Some shops might lock the tune if they use their interface.

Don't get the TDN device. It severely limits you to specific shops and you can't see, read or write to your car until its unlocked by that shop.
