Bartels Auto will go above and beyond for the customer. The team there will walk you through the errors you are experiencing, they will show you the error if it is visible. My problem was. The actuator on my Holley performance exhaust was disconnected from the system. Bartels did not have a spring for the device, so they were able to get this tied up to the system so that it does not throw codes. No dealer across the entire area would have such a spring. The team at Bartels went above and beyond for me.
