  • ⚠️Quick Note

    Don’t worry — this form looks longer than it really is. Most questions just help us get your base tune closer so the process goes smoother and needs fewer revisions. The only mission-critical info is marked with a red asterisk (*). If you’re unsure about anything else, just fill in what you can — we’ll review it and follow up if needed. 

    If there’s anything you think we should know that isn’t specifically asked, please include it in the Additional Information section at the end.

    We’d always rather have too much info than miss something small that could make a big difference.

  • Injector Requirement

    Due to cheaply manufactured, re-drilled, and de-capped injectors causing more problems than they're worth, we will only tune a few specific brands of injectors. These supported brands have a proven track record of consistency, reliability, and quality injector data. The injectors listed in the NOT Supported list are there due to firsthand experience with injector related performance/reliability issues from that brand/supplier (including, but not limited to, firsthand experience of uncorrectable drivability issues, startup inconsistency, injector failure, and a direct cause of catastrophic engine failure).

    We will happily provide quality injectors with quality data, if needed.

  • Tune Type

  • We offer 4 different options for getting your vehicle tuned:

    Street, Remote, Dyno, and Bench

    Please see our page Comparing Tune Types to determine which is the best option for you.

  • WARNING:


    Your vehicle's level of modification would greatly benefit from a complete remote tune or full custom dyno tune. The other tuning options are adequate for a base tune, but we strongly recommend a more in-depth solution for the final tuning.


    With this in mind, feel free to update the type(s) of tuning above as you see fit.
