Kit includes:_x000B_Software (Fast Load)., FVD Race Muffler (Cat Bypass), Sport Headers, Sport Turbochargers, BMC Sportfilter_x000B_Endtips BES 997 160 41S must be ordered separately._x000B__x000B_Tuning:_x000B_Max. Power - 448kW (610HP) @ 6000rpm_x000B_Max. Torque - 805Nm (594lbf ft) @ 4750rpm_x000B_Max. Speed - 335km/h_x000B_Max. RPM - 7100rpm_x000B_Acceleration 0-100km/h - 3.4s_x000B__x000B_In different Situations with tiptronic cars the maximum power will be 580HP. But the maximum Power of the Engine stays at 610 HP. To protect the transmission the Tiptronic DME will regulate the power to maximum 580 HP._x000B__x000B_We program our ECU's with the following modifications in mind:_x000B_Removal of the top speed limiter_x000B_Increasing the rev limiter_x000B_Modifying ignition timing_x000B_Increasing throttle response_x000B_Optimizing Air / Fuel Ratios_x000B_Modifying boost mapping (Turbo Cars)_x000B__x000B_We tune all of our performance products as well as our proprietary software on both an engine and chassis dyno to ensure accurate performance numbers and unparalleled reliability. We are currently using:_x000B__x000B_FVD Headers_x000B_Made of V4A (T316) Stainless (More corrosion resistant than T304)._x000B_Header tubing features a merge collector to channel exhaust gases for maximum torque gain!! Gains 15 lb. ft of torque._x000B__x000B_Our Variable geometry turbocharger (VGT) is designed to allow the effective A/R ratio of the turbo to be altered as the conditions change. This is done as the optimum A/R at low engine speeds is very different to the optimum at high engine speeds. By altering the geometry of the turbine housing as the engine accelerates, the turbo's A/R ratio can be maintained at its optimum. Because of this, our VGT turbochargers have almost no lag, have a low boost threshold and are very efficient at higher engine speeds._x000B__x000B_This exhaust is the least restrictive muffler of all of the FVD offerings. The Race Muffler produces the most power and a phenominal sound! This exhaust is for the person who really wants to hear the deepest growl from the 997TT engine with the turbos spooling!!_x000B_Made of T316 Stainless(Increased corosion prevention over T304) with Catalytic Bypass (without cores)._x000B_The Muffler will not crack under the extremely high heat off of the turbos due to our advanced mesh integration._x000B_This System Weighs 37lbs and is completely modular which allows you to swap to a 100 / 200 Cell Setup or a complete FVD Race Pipe Setup (Muffler Bypass)._x000B_Reuses Factory tips or any other aftermarket tips that fit on the stock exhaust._x000B_DME SOFTWARE UPGRADE IS NECESSARY as you will set off the Check Engine Light without one.
