As always you get the support from everyone here at BTuned Performance. We pride ourselves in our work and customer service. We strive to ensure the calibration of your vehicle goes smoothly. We send the stock calibration to your vehicle so you will be able to flash your car back to its factory file leaving the calibrated file practically unnoticeable. Though we try to get revisions done as quickly as possible it can take 24-48 hours before I can review your log/email. Please work with us as we are very busy and want things done properly. Any updates, requests or questions regarding your tune should be included with a log of your vehicle to Btuned.sales@gmail.com
