Shortly after turbo charged cars became a mainstream build the tuning industry really took off! Most of these cars require similar parts to take them to the next level of power, thus it became easier for a car to be known as Stage 1, Stage 2, or Stage 3 tuned, an easy way for a company to sell products to a customer and an easy way for a customer to tell others what power level their car is at.
Normally ‘Stage’ tunes follow the build sheets below.
Stage 1 – Software requires no additional parts other than a healthy engine.
Stage 2 – Software requires a free-flowing exhaust and an induction kit. Supplying the engine with more air and the ability to increase combustion.
Stage 3 – Normally requires the introduction of an intercooler, on some cars this can also be a turbocharger and fueling changes.
