This tuning package consists of a high-flow cotton drop-in panel filter, Shark Werks muffler bypass system, and EVOMSit ECU Tuning with a handheld TUNEit module. These components combined will increase your performance while maintaining engine reliability and driveability, and give you an extra 15-18 HP and 20-25 TQ. This is the perfect addition for the street and / or track-driven 991 GT3 / RS / R.
The EVOMSit ECU Tuning for the 991 GT3 / RS / R has been tested under the most gruelling conditions during dyno test simulation and during real-world driving on the street and track by the EVOMS & SharkWerks team drivers as well as through our eDRIVE independent product validation program. Rigorous testing under extreme conditions has been conducted and evaluated with various fuel octane grades in the heat of the dry Arizona desert, the cool temperatures and humid weather of the California coast, the high elevation of the Colorado Mountains, the heat and ocean humidity of Mexico and the frigid elements of Minnesota. This stringent and gruelling method of testing assures pure, crisp and consistent power in all of the conditions that drivers demand.
The Evolution MotorSports performance systems for the 991 GT3 / RS / R utilize the Intelligent Tuning of EVOMSit. A tremendous amount of time was spent fine-tuning the software for 93 and 98 RON fuels. All performance figures are based on 91 octane and power gains for 93 octane settings are slightly higher. A considerable amount of time was dedicated to the E-gas settings which have been optimized in both sport and non-sport modes. We improved throttle response in both modes which provides an incredibly crisp throttle response while maintaining perfect drivability.
Not only are the power gains and overall performance impressive but we were able to improve the power while utilizing 93 RON fuel. Additionally, we have calibrations for larger displacement 3.8L engines and full race programs, all of which utilize our IST (Integrated Switching Technology) and SP (Sport Pedal) functions.
The EVOMSit TUNEit handheld unit is included with your ECU Tuning purchase. This unit allows you to download and install our performance software via your car's OBDII diagnostic port. Simply plug in the handheld unit via included OBDII cable, read out your file, and email it to us. (Access to an email-enabled computer with a USB port is done via the included USB cable.) We will email you back (usually within 24 hours) a performance file that you can upload yourself.
NOTE: Installation requires the use of an automobile BATTERY CHARGER (10+ AMP)

IST (Intelligent Switching Technology):
IST is an OEM feature that is built into the factory ECU and allows for automatic switching of ignition timing maps based upon input received from other engine sensors. Available for certain EVOMSit performance programs, the EVOMSit IST programming incorporates this intelligence for true and safe flexible power without compromise. The EVOMSit ECU tuning utilizes the multiple OEM ignition tables in progressive stages, which can optimize safe performance based on outside conditions and different octane fuels. The ECU automatically switches to the best-suited ignition map creating an automatic “race mode” if race fuel is utilized. This IST function is always active and will switch automatically without having to physically change anything. IST is far more intelligent than any manual switcher found in the market. The use of manual switchers can cause serious engine damage if accidentally switched to a “race mode” without having race fuel in the car. This manual type of switching technology physically locks the timing map and can override the ECU’s ability to protect itself if unfavourable conditions exist. This manual switching is archaic considering that OEM ECU has the ability to analyze conditions and switch timing maps automatically.
SP (Sport Pedal):
All E-Gas (drive-by-wire) cars from model year 2000 and newer have an electronic throttle valve, which is controlled by the car's ECU. Available for certain EVOMSit performance programs, EVOMSit Sport Pedal™ (SP) feature changes the ratio of accelerator pedal movement versus opening of the throttle valve which will increase throttle response. By modifying these maps in the ECU calibration, throttle response is drastically improved and the “throttle delay” which is a common complaint among enthusiasts is eliminated. Certain cars contain an OEM “sport mode” which incorporates this same Sport Pedal™ feature. For these cars, we incorporate the OEM “sport mode” pedal calibration for the regular mode and further increase the responsiveness of the “sport mode” with our improved calibration.
