How this works

It’s an easy process. If you come to us, we can do a road or dyno tune (dyno tune is subject to dyno availability and will have additional fees). Takes about an hour and you’re done. You can also rent the equipment from us and get tuned no matter where you live!

Equipment rental comes with easy to follow instructions and you can do everything yourself right in your driveway. We provide the tune, no tuning experience necessary. After you’re done tuning, you ship us back the equipment. Once we get the equipment back, you get a refund for your deposit. 

Pops and Bangs / Flames

There is no guarantee on pops and bangs. We cannot control the quantity, volume or duration of the pops and bangs. Every car is different and you might get more pops, you might get less.

No refunds if you don’t like the pops/bangs after tuning.

We do not guarantee you’ll shoot flames and we do not offer flame maps. Please don’t ask.

E85 Tunes

We offer E85 tuning! You will need a wide band, an ethanol content sensor and an E85 kit.  We will not tune you if you do not have a wide band and content sensor. Depending on your car, you may need larger injectors to support E85.

Refund Policy

No refunds on remote tunes for any reason once you have been sent a tune file. You may request a refund at any time before that. Shipping costs will not be refunded.

Tuning done by us in person can be partially refunded, but only after the stock tune has been flashed back to the ECU.

Disclaimer & Risks

Tuning your ECU requires specialty equipment and processes that may results in a bricked ECU. We do take every precaution necessary to try and prevent this, but the risks are still there. In the event of a bricked ECU, you may need to purchase a replacement ECU or send your ECU off to get repaired which will incur additional time and cost.

Changing your factory tuning parameters can be dangerous and can result in damage to the engine and/or other parts of your drive train. We work with experienced tuners to avoid these types of problems, but there is still the risk of engine damage caused by improper installation of parts, incorrect information provided to the tuner about your mods and changing your mods after the tuning process. If you plan to make changes after your tune, let us know BEFORE you get tuned!

Changing your factory tuning parameters can result in your warranty being voided by the dealer and/or 3rd party insurers. We keep your original factory tune on file in the event you need to reflash back to stock, but this will incur an additional rental/flash fee.


By placing your order, you are  acknowledging that you accept all risks and agree that neither 3point8 Performance, nor the tuner are liable or responsible for any damage for failures that may results from the tuning process, or the tune itself. This includes, but is not limited to, engine damage, bricked ECUs and any additional costs involved in the process (e.g. new ECUs or ECU repair, replacement of damaged parts, loss of warranty).
