Ford Mustang GT Stage 1 Remap
On Ford Mustang GT 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. GT engines with 300–450 bhp reach 320–468 bhp with a Stage 1 remap; the largest gain is +25 bhp (GT 5.0 V8 420hp). Pick your version in the table below.
