3 Days to Maximum Power Share Comments 3 DAYS to Maximum POWER! The ultimate APR chip upgrade for your Volkswagen and Audi is available effortlessly from ECS Tuning. Available in 91, 93, 100 and 104 octane specific programs. Want chipped mode? Want to be able to switch back to your stock settings? Want a race mode to run 100 octane fuel at the track? How about a valet mode that limits power? EMCS, a feature exclusive to APR, allows you to switch programming options right from the cruise control stalk of your vehicle. ECS has simplified performance chipping. No need to run around town setting up a UPS account or standing in line at the post office. Order your chip online at ECS. Shortly after placing your order you will receive an e-mail containing a prepaid UPS Next Day Air shipping label, print the label, attach to your package and drop it off at any local UPS Store (formerly Mailboxes etc.) or any UPS drop box (ECU’s should fit no problem). In as little as 3 days you will have your ECU back in hand ready to drive. The FREE shipping doesn’t stop there. The day your ECU is received by ECS we will immediately install the APR chip and program it to your desired specifications and get it back in the air for next day delivery to your door. By removing and installing your own chip you save from paying any additional labor charges. Install your ECU and drive. No special tools required to complete the job. APR chips are ready to go right out of the box. For more details, visit our website.
