JDM Engineering 2015 Mustang GT Tuning ON SALE

This sale is limited to N/A applications for automatic and manual transmission cars with Bolt-Ons.

JDM Engineering 2015 Mustang GT Custom SCT Tuning

Manual transmission cars can expect greatly improved throttle response with more horsepower and torque throughout the curve with smooth drivability.

Automatic transmission cars are our specialty! Engine tuning is relatively easy..Creating and auto trans tune that performs well and drive nice also takes skill. With our 2015 A6 shop car we have the 6R80 dialed in to run fast and smooth consistently as seen from our testing below.

Auto trans customers can expect huge improvements in throttle and transmission response in relation to pedal input. Part throttle shifting will be firmer and quicker giving a more sporty feel to the car. Wide Open Throttle shifting is lightning fast for the best E/T possible without being too firm for every day street driving.



If you are looking for a high performing, smooth driving and safe tune for your bolt-on 2015 Mustang GT M6 or A6 JDM Engineering should be your choice.

Nick, I made a post on your FB page a few days ago about the price of your tune being expensive compared to other options. I am glad to see you guys are running a sale. I do have some questions though.

Does your tune have the adjustment options unlocked? Such as axle ratio, tire rev/mile, rev limit neutral, global spark, WOT shift 1-2, WOT shift 2-3 and so on?

What do you charge for tune adjustments for changes made to the car later? Like stall converter, headers, E85, CJ intake manifold and so on.

Than you!

When we send out tunes we typically allow control of non engine functions. Axle ratio, tire rpm, shift firmness ect are left open upon request. Spark, AFR and more sensitive controls are not unless it is a dedicated race tune for track use only.

Tune adjustments can range from $50 to $125 depending on how many changes need to be made. Requested changes to the initial tune file upon request are free of charge.

Thank you for the info.
