Burger Motorsports JB4 Performance Tune VW / Audi / Skoda – AutoInstruct

Anyone with a JB4 fitted to a VW still under warranty: Do you pull the OBD cable out through the firewall each time before service or just tuck it away? ... I'm trying to decide between JB1 & JB4 and presently, JB1 seems that bit easier to put in/remove before & after each service.. but I hear the power delivery of the JB4 is a bit more linear (read smoother)... maybe the JB1 is an easier/stealthier option for now...

JB1 is super easy. Get some low rise car ramp extensions to lift the nose up and you can get removal down to under 10 minutes. Takes a little longer to reinstall (for me anyway) as I am the cable tie king. Everything needs to be neat and tidy and all squared away. If you don’t care about that, then not much more to reinstall either. Completely invisible power gain!
