Evolution Motorsports is proud to announce EVOMSit Software for the 991.2 Turbo S!

Porsche built the "580 hp" 991.2 Turbo S with uprated intake manifolds, fuel injectors, higher fuel pressure, and most notably larger turbo compressors compared to the previous 991.1 Turbo and Turbo S models. These factory improvements were a very welcome addition to the platform based on what we learned working with the 991.1 Turbo, although the claim of a mere 20 hp increase over the previous model didn't pass the sniff test.

Indeed, when we did GPS acceleration testing on the street and baseline power testing on the dyno, we found the performance of the new Turbo S was extraordinary and well beyond the factory claims. 50-100mph, 60-130mph acceleration, and peak dyno numbers were all just shy of the performance of our 991.1 Turbo EVT640 kit, and we calculate the car is actually producing closer to 625 hp as tested with a completely stock car on 91oct fuel! With that knowledge we carried out a development program to build a range of performance packages aimed at improving and amplifying the strengths of the new Turbo S without sacrificing any of the everyday usability or reliability it is renowned for.

Options and Power Ratings

Power gains, hardware requirements, and fuel ratings for most available files are shown below. Power ratings are estimates of crank horsepower based on results of dyno testing and performance on the street. Performance may vary depending on fuel quality, environment, hardware quality, and vehicle condition. Custom tuning is available for certain applications with an additional fee; contact us to discuss.

How to Purchase and Install

EVOMSit software includes the TUNEit OBDII Handheld Flash Tool to facilitate installation and allow user to switch between Stock, Pump, and Race gas programs at users' leisure. Upon purchasing software, the flash tool is shipped out. After installing software on a Windows computer and running updates, the TUNEit tool is mated to the car during a brief process. After sending over the identification from the TUNEit tool, we create and send back the pump and race gas programs to be installed on the car and use at your discretion. Reflashing the car between files is a simple process that takes a couple minutes to complete.

EVOMS Tuning Philosphy

Founded in 2000, Evolution Motorsports has specialized in modifying watercooled 911 Turbos since the release of the 996 Turbo. Since bringing ECU tuning in-house under the EVOMSit banner in 2008 we remain one of the only exotic car tuners to develop both hardware and software upgrades together in tandem. This allows us to design software with a better understanding of the design, capabilities, strengths and weaknesses of the hardware over which it controls from the air filter to the engine internals. Our 991.2 development program is built on lessons learned tuning DFI Porsches dating back to being the first tuning company to get a 997.2 Turbo into the 10s back in 2010 through our findings during the creation of our 1000whp EVT1100 package for the 991.1 Turbo S.

During our our initial and ongoing R&D process we create, test, and refine a catalog of tuning files designed to suit a variety of different popular hardware combinations and fuel qualities. Each of these files is rigorously tested on the dyno and street using professional tools and expertise to ensure they the best performance and reliability possible throughout an array of different situations and scenarios. For example, at one point we developed a file that performed exceptionally well on the dyno, but found that it performed poorly on the street due to how the car reacted to heat build up over longer full throttle runs. The software was asking more than its matching hardware could support in the real world. A different approach made slightly less power on the dyno produced far better performance on the street over every type of driving it was tested under as it maintained the car under the temperature thresholds where the ECU would pull back power. By doing this kind of diligence up front, we can deliver tuning for a variety of applications that works well out of the box without having our customers shoulder the burden of testing and developing a file for their car and usage as typical 'custom tuning' requires.

Every tune we produce is made to order from our catalog of files to suit the needs of the customer and their car. Our tuning process starts by filling out a four-page questionnaire to gather detailed information about what hardware upgrades the car has, what kind of fuel is used, and how the customer drives the car (purely street use, straight line racing, road course use, some combination of, etc.). This information is used to issue a tune best suited to the unique requirements of the customer and their vehicle.
