Due to recent events, we have revised our ECU hardware and software support for Subaru. Certain tuning software suites are no longer supported for all applications. Market conditions have resulted in a 13% rate increase (the first in nearly six years). If your vehicle is not listed on this page, it is not supported. If you have questions after reading this list, please contact us.

The following policies apply to all customers and jobs unless stated otherwise.

Down Payment/Deposit Policy

All customers required to give 50% deposit, whether they are live or e-tuning customers. For live customers this deposit serves to secure the appointment. For e-tuning customers this serves as payment for a base tune to get started. Final 50% to be paid upon completion if not forfeited (see below).

Upgrade Policy

Existing customers receive 25% off upgrading between stages. Upgrade pricing must be approved in advance. Example, going from stage 2 to stage 3 would take 25% off the stage 3 rate.

Seasonal and Weather Revisions

Customers entitled to one hour free revision time in order to account for seasonal or weather changes. Example: car tuned in summer needing a winter revision for overboost, or other condition.

Mechanical Issues Preventing Successful Tune

If tuning cannot be completed because of mechanical issues or installation error, a $75 fee will be incurred at the time of stoppage. This policy is waived if a pre-tune check has been performed and approved 2 weeks prior to tuning date. Pre-tune inspection must be performed by approved technician. Contact for a list of approved sources.

Scheduling

All work shall be completed by appointment only. Monday through Friday only, excluding holidays.

No-Call/No-Show Policy

No-call and no-shows will forfeit their 50% deposit unless written cancellation is submitted in writing at least 2 business days in advance of appointment. Reschedules following NCNS will be placed at the back of the customer queue.

E-Tune Policies

E-tune customers final 50% payment due when tuning has been completed to the satisfaction of both parties. If customer does not provide new iterative/revision logs within 2 business days of being requested by BW Tuning, the job is assumed to be complete and final payment is due. No base map will be shared without an initial 50% deposit. If no initial logs from the base map are received within 7 business days, the job is assumed to be vacated and the initial 50% deposit will be forfeited. If you are unable to comply with this schedule due to legitimate reasons please contact us and discuss up front, we try our best to work with everyone's unique schedules.

Status Updates & Checkups

We will contact all customers when information is needed or there is news to share. Periodic, informational updates shared at our discretion. Updates related to appointment coordination related activities or payment related issues will be shared ASAP.

Communication Preference

Customers are encouraged to use email when possible. Phone/text to be reserved for appointment coordination related activities or emergencies only.

Liability Statement

Modifying vehicles is an inherently risky and dangerous hobby. BW Tuning does not take responsibility and shall not be liable for any damages incurred during or after live tuning, e-tuning, or any ECU modification work in perpetuity.
