Opel Astra 2.0i Stage 1 Remap
On Opel Astra 2.0i naturally aspirated engines a Stage 1 remap refines the ignition timing, fuelling and throttle response maps. Without a turbo the power gain is smaller than on turbocharged engines; the difference is felt mostly in throttle response and the mid-range. No hardware is changed and the original software is backed up.
It depends on the generation and the stock output. 2.0i engines with 136–160 bhp reach 146–170 bhp with a Stage 1 remap; the largest gain is +10 bhp (G 2.0i 16v 136hp). Pick your version in the table below.
