What is a bypass plug?

A bypass plug is a small plug that connects to the end of the harness in place of the tuning box. This allows the user to return their engine back to stock mapping without removing the wiring. This is a useful adapter if the sensors are difficult to access.

For Diesel vehicles we expect to see improvements in fuel economy of around 10%. This means if you currently get 50 MPG you might expect to see somewhere around 55 MPG. This is very dependent upon your driving style. If you use the extra power and drive faster naturally the economy benefits will be lessened.


The original 2 year warranty is still applicable to units that have been reprogrammed. Units that are beyond the original 2 year warranty period will be covered for hardware failure for 1 month. Reprogramming is not part of our 28 day money back guarantee and are non refundable.
