Stage 1 includes a JE developed performance ECU remap and to ensure maximum air flow we also include an ITG performance air filter element.
 
Stage 2 includes a JE designed High Flow aluminium intercooler which is almost 50% bigger than standard and ensures the engine gets the maximum amount of cool, dense air possible. We also tweak the ECU remap to take advantage of this larger intercooler and, as always, we fit an ITG performance air filter element.
 
(Please note that in common with all electronic software upgrades, the improvements inevitably depend on the age, mileage, and condition of the engine. The output figures quoted here are based on tuning work on engines in premium condition, so they must only be used as a guide to the results obtained.)
