Porsche 911 3.8i Stage 1 Remap
On Porsche 911 3.8i 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. 3.8i engines with 430–560 bhp reach 450–600 bhp with a Stage 1 remap; the largest gain is +80 bhp (3.8i Turbo 520hp). Pick your version in the table below.
