diagnostic service using our Dynojet rolling road facility.
We are an approved and fully authorised Dynojet Power Commander motorcycle dyno tuning centre serving Bristol and the south west.
Our technicians are fully trained and certified by Dynojet
Using the most up to date Dynojet 250i dyno in our air-conditioned facility we can

In combination with the very latest tuning link software we can supply and install
the Dynojet Power Commander
or the Bazzaz engine management, quickshift and
traction control unit, for any
motorcycle. These units enable us to accurately set up the fuelling and ignition to achieve optimum performance.
We also offer a procedure that enables making mapping
adjustments directly into the ECU.
Direct ECU fuel mapping/re-flashing now available from £349, no need to purchase any additional fuelling module – call us for more information
