Below is a bunch of information about tuning and the process, what is needed to prepare your vehicle, and how to get on the schedule.

In April of 2022 Cobb released an update that no longer allows us to tune with the old flex fuel designed systems or disable any check engine lights with the Accessport. We can still tune with an Accessport, but if you have any emissions deletes you will have codes for those i.e. TGV, Air Pump, EGR deletes or catless/ non GESI catted Down/J-Pipes. More information can be found here. We also have no more support for V2 Accessports.

The most current prices can be found here.

Our pre-tune checklist can be found here. (I recommend reading through this first before you schedule a tune to be sure your car is ready to go and your tune goes smoothly.)

Detailed modification guides can be found here. (We cover STI, 2015+ WRX, BRZ/FRS, and the EVO X. We list the parts needed along with dyno graphs showing expected power at all the different modification levels.)

If you need anything done by us on that list prior to the tune you will want to schedule it with us before so it’s ready to strap down and tune at the time you’re scheduled for.

We schedule tunes at 8 am and 12 pm daily during the week for appointments. We do collect a $100 non-refundable deposit to hold a tune spot. You can pay over the phone with a card by calling 763-316-5882, via PayPal to this email (jesse@jmautomn.com), or on our web store here. If you pay via PayPal or on our web store, the tune spot is not held until you make payment. Once payment is made with PayPal or our web store, we will contact you to confirm the date and time.

We are usually on average a week booked out all winter for tuning. The average engine build takes about 3 weeks to complete from start to finish.

Let us know if you have any questions or would like to schedule an appointment.
