The 2008 Porsche Cayman S is a Tiptronic that runs on 91octane. As soon as the car came here, we did a baseline on our Mustang Dyno. Our baseline run yielded 217rwhp and 197ft/lbs of torque. Our Stage 2 mods consisted of the Racing Plenum with ECU Flash and a complete exhaust system with catless race headers. The plenum kit uses a larger throttlebody to improve the airflow coming into the engine. To fully take advantage of this, we do a custom ECU tune to alter the fuel and timing maps to account for the additional air flow. Like all normally aspirated vehicles, a good balanced exhaust system definitely helps out as well. We alter the limits on the O2 sensors to not throw a CEL from this catless setup. With all the new mods on, we did a follow up dyno. With all other variables kept consistant, the car made 252rwhp and 217ft/lbs of torque. That is a 35rwhp and 20ft/lbs of torque gain. Typically there is a 10-15% drivetrain loss on the Mustang dyno and since this is a Tiptronic and on 91octane, the results would be even great with a 6spd on 93octane. Overall dramatic driveability improvement and much better sound!
need ECU tuning for Cayman S 2010.

Would it make any difference if i was using 98 octane fuel? Can the ECU tuning be maximised to 98 octane fuel?
Your 98ron is 93oct so is the same.
