Porsche Cayenne S 4.8L V8 DFI – $1295
The 2008 and up Porsche Cayenne is a big change over previous models. The new Cayenne S has switched from a Bosch ECU to now running a Siemens SDI system. The new 4.8L engine in the Cayenne S is much more powerful than the previous generation.
With stock 385hp at the crank, Softronic has developed tuning to give the Cayenne S power like its bigger brother, the GTS. Another 33 horsepower and 21ft/lbs of torque to the crank is added. Softronic has spent time engineering and developing software for the new FSI cars and is one of the only tuners in the world that can offer an ECU flash via the OBDII port.
Cayenne S Stock Power – 385HP and 369ft/lbs
Tuned Power – 418HP and 390ft/lbs
"RENN HAUS performed their ECU upgrade/flash on my Mercedes with a K&N air. Results were a healthy increase in horsepower (25hp) with a boost in acceleration especially in 2nd through 4th gears. It is a lot more fun when merging on the Interstate now. Off the line acceleration has improved and highway cruise gas mileage has improved. Normal driving is seamless, smooth and transparent to the driver. But put your foot into it and the result is immediate and smooth. The responsive interplay between the ECU management of the engine and the 7 gear electronic transmission results in GO! GO! GO!!!!!
GUY COVINGTON and his folks at RENNHAUS made this customer happy!!!!!!!"
