With the TP420R Package power is raised dramatically while maintaining warranty as it is completely undetectable when removed due to the advanced active reset technology. We also have upgraded the internal circuits to allow quick response and provide endless miles of driving without the worry of the car not working as it should.

Our systems are tried and tested worldwide to ensure reliable sevice for years to come. The latest version is based on the New V4 Hardware. Packed with advanced features including RPM over run protection and Warm up mode it looks after your car while giving you real power gains.



The system comes pre loaded with Stage 1, 1.5 and 2 so just add the hardware as you go.
