TUNING & PROGRAMMING

We support HP Tuners, EFI Live, Holley EFI, Haltech, & FuelTech systems.

No — most tunes are delivered remotely via email or Anydesk software. You can also ship your ECM/TCM to us and we can flash a file to suit your needs. In-person dyno tuning is available for advanced builds requiring real-time calibration and in that instance your vehicle would need to be present at our shop.

Aftermarket tuning can affect powertrain warranty coverage. We recommend reviewing your dealership's warranty terms before tuning a vehicle still under factory coverage.

Every vehicle is different. If your vehicle is correctly configured, it can take a couple of hours. Alternately, if your vehicle is a mess, it can take literal weeks to diagnose all the issues and address them correctly to the state where tuning can be finalized.

ORDERS & SHIPPING

In-stock parts ship within 1-2 business days. Custom tuning files are delivered digitally once completed, typically within 1 business day.

We generally do not ship internationally. Please contact us on what you want to order and we could make something happen for you. We tend to deal with this on a case by case basis due to the complexity and risk associated.

Yes — you'll receive a tracking number by email as soon as your order ships from our shop or B2B vendor.

Contact us within 48 hours of delivery with photos of the damage. E-mail is preferred to keep a log. We will investigate with the courier and follow up with a solution.

Expedited shipping options are available at checkout for most in-stock components. Some items are customizable and will ship in an "expedited" form only AFTER the item has been completed/built.

TRANSMISSIONS & POWERTRAIN

We offer both — fully built eady to install, as well as individual components like torque converters, valve bodies, and shift kit components.

We build GM 4L60E, 4L80E, 6L80E, 6L90E, TH400 & Powerglide transmissions. We provide tuning support for most longitudinal electronic domestic transmissions including:

4L60/80E | 6L80/90E | 8L90E | 10L80/90E | 6R80 | 10R80 | 8HP | NAG1 | ALLISON | 68RFE

Each "stage" is rated for a specific horsepower and torque range. Tell us your engine's output and intended use (street, strip, towing) and we'll spec the right build.

Yes, all built transmissions include a limited warranty covering internal components against defects in workmanship. It does not include warranty against improper use or installation. For more details on what constitutes improper use or installation, please contact us.

In most instances, yes. There are some modules that require an unlock service beforehand. These are generally on vehicles newer than 2017 (GM vehicles mostly).

RETURNS & CANCELLATIONS

Unused, uninstalled parts in original packaging can be returned within 30 days of delivery for a refund or store credit. We can't offer a refund if the parts were installed, and or used.

Custom tuning orders can be cancelled before work begins. Once a tune is in progress or completed, it is non-refundable due to the labor involved. This is why it is important your vehicle is TUNE READY before you purchase any tuning services. We can't issue a refund if we instruct you to address certain issues and you choose to not follow up.

Electrical parts (ECUs, TCMs, sensors, wiring harnesses) can only be returned if unopened and uninstalled, due to their sensitive nature.

Customers are responsible for return shipping costs unless the item arrived defective or we shipped the wrong part.

Refunds are processed within 1-3 business days of us receiving and inspecting the returned item.

TECHNICAL SUPPORT

Yes, our technical team is available to walk you through installation questions for any part or tuning file we sell. We recommend you e-mail us as we are a small team and handle daily operations within the shop. If you decide to call and we do not answer, please do not hesitate to send a text message so we can follow-up once we are available.

Basic diag is included with the purchase of our tuning services. Keep in mind that most CELs are a result of MECHANICAL ISSUES and not programming issues. We will try our best to provide accurate work-flows to properly diagnose and fix your CEL. A TUNE IS NOT A FIX-ALL SOLUTION TO YOUR PROBLEMS.

Reach our technical support team by email or phone during business hours, listed on our Contact page, for the fastest response. If you have difficulty using e-mail and gave us a call, but there was no call back, please send us a text message to the same number.
