Porsche 911 GT3 Stage 1 Remap
On Porsche 911 GT3 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. GT3 engines with 415–500 bhp reach 435–525 bhp with a Stage 1 remap; the largest gain is +25 bhp (GT3 500hp). Pick your version in the table below.
