STAGE 1
It is recommended for GTI owners that wish to drag race their vehicles to use the Boost By Gear file. The limited boost/torque requests in 1st, and 2nd help reduce 60 foot times and 0-60 times.
MK8 EA888.4 (EVO4) is not yet supported on FZL. Tune delivery is only possible through an official TuneZilla Dealer that is equipped with a CMD Flash tool. Or by renting a CMD tool through the tune purchase process.
Fuel requirements for Stage 1 are based on customers installed hardware. On the EA888.4 using stock hardware, 91 octane is optimized. There is no additional performance gains with a higher octane fuel on stock hardware. To optimize 93 Octane, we require that an upgraded intercooler is installed to decrease (IAT) Intake Air Temps. This is often referred to by other companies as "Stage 1+"
STAGE 2
Stage 2 is optimized for Shell 93 Octane (Canadian). But also requires an upgraded intercooler and downpipe to see the advertised gains.
