TPC Racing Stage 1 991 Carrera S ECU Tune

What a fun tool these Accessports are for the newest gen Porsches! After some pulls on the dyno using the Cobb tune, Mike spent some time optimizing the CAM and ignition timing tables to maximize the potential of the 3.8L NA flat six Carrera S engine. We were able to extract an additional +18 horsepower to the wheel over the stock tune at max power output. We saw peak gains as much as +21 horsepower to the wheel. The tune is a very linear increase in power, not sacrificing power in any particular range to gain in another (ie., at no point in the rev range does this tune produce less horsepower than stock).

TPC Racing continues to expand its line of OTS stage 1 tunes via the Cobb Accessport for the 9x1 platform.
