Full custom WTF Dyno Pro Tune for your 2015-2018 DIT (Direct Injection Turbo) Subaru WRX on our AWD Mustang Dyno utilizing the COBB Accessport (customer provided or purchased through us). Please make sure to check the email address you use during checkout for an email from us as we will reach out to confirm scheduling before your appointment. If you have any questions, contact us here.

Our dyno tune option is a drop off / pick up service only as our dyno is located in Tooele at our UMC track garage facility, separate from our West Valley City service facility. No customers are allowed inside our dyno bay for insurance and safety reasons, but video footage of your car can be provided if you request it in advance. 

Within 2 business days (48 hrs M-F) of purchase, our team will contact you to go over the details of your car and set a tune date based upon the ready date of your car and our schedule availability. If you wish to expedite the process, you may call or email us directly to see if we have an inspection and tune slot available.

Vehicles may be dropped off any time before 10 AM on the scheduled tuning date. An after-hours key drop is available. Vehicles may be picked up the next business day (M-F) between 10 AM - 6 PM (normal business hours).

If your vehicle does not pass our Pre-Tune Inspection and an immediate fix cannot be made to rectify the deficiency, we will notify you immediately and your tune will need to be rescheduled to a later date. Because of this, we encourage setting a separate appointment for the inspection and this will be offered up when we contact you after your purchase is made.
