Pricing and Information

• All custom tunes on this page are priced by Wester's Garage at $595 (bench tune or street tune) and $695 (dyno tune). Call or e-mail for discounted ExaTorq pricing.
• If you do not find your GM vehicle on this list, please check the Class 2 list.
• In-vehicle and bench tuning is available for most vehicles on this page. Add $50 for ECM swaps; no additional core costs apply for in-vehicle tunes or tunes using your supplied ECM.
• An additional cash deposit or charge card authorization of $350 is required for ECM swaps to cover the cost of our ECM should it not be returned within 30 days.
• If you send us your vehicle's ECM, processing time is within one business day after receipt. Please note that the turnaround time for a non-stock (not from your vehicle) or blank (from the GM dealer) ECM is approximately one week.
• Stock flashes for any vehicle on this page are $70. There is no extra charge for stock flashes in conjunction with a custom tune. We can only flash on-the-vehicle at this time.
• Ground shipping via FedEx is included. For any other shipping methods, you pay the difference between actual shipping costs and FedEx ground.
• We can tune for just about any engine modification on the vehicles in this list (greater displacement, cams, long-tube headers, etc.). The engine displacement in this list refers to original displacement prior to modifications.
• For GM vehicles not listed here or on the Class 2 list, please contact us, as we are constantly updating our application list.
