GIAC 91/93 octane software is now available for the Porsche Carrera GT!
First release software combined with an exhaust upgrade provides an additional 18 - 21 HP and 15-20 ft-lbs of torque (at the crank shaft) over stock based on 2-wheel dyno results (626HP and 456 ft-lbs). The gains are found throughout the useable power band, 2000 to the new rpm limiter of 8600, and can even be felt at half throttle. Drivability remains as smooth as stock.
An official dyno plot generated from testing is attached. The dyno plot depicts two runs:
GIAC performance software for 91 octane with GMG exhaust, and
baseline stock software and exhaust with 91 octane.
Thanks to GMG for first class hardware and providing the Carrera GT used to generate these dyno plots.
