Satera Tuning handles the install.

Want it installed? Our technicians can install it at our shop in Marengo, IL, and we tune it on our in-house chassis dyno, by appointment. Street tuning dials in drivability.

Not local? Many Mopar and Ford combinations can be tuned remotely with HP Tuners.

Submit a work request and we'll confirm fitment, install and tuning for your car. Shop rates are listed on our Rates & Terms page.

Lead time depends on the manufacturer and on our shop schedule, so it varies by part. If you need something by a certain date, contact us before ordering and we'll check current availability.

See our returns and warranty policy for the details on returns and exchanges.
