With the Astra J being so fresh to the market, we will be slowly releasing our Stage 1 upgrades for the 1.4, 1.8 and 2.0 models, followed by the CDTI models also. We will also be developing Exhaust Systems and Intercoolers for the Turbo charged models, and offering Stage 2 re-maps later in the year.
