Stage[1] consists of a software upgrade only, no additional parts are required. The software is calibrated to maximize performance while operating within the stock fuel injectors' flowrates and stock turbo efficiency range. The longitudinally placed 1.8 liter 20-valve turbo utilizes 299cc/min fuel injectors, compared to 317cc/min fuel injectors equipped in the transverse version. The smaller injectors become a limitation when trying to run higher boost pressures.
Peak Boost 17psi to 8psi by redline, Rev limiter set to 7200rpm, Speed limiter removed
