Coming from the factory with 530bhp in this Porsche Turbo S, it was already at a new level of quickness. When I bought this car it actually had a GIAC ECU Flash on it with their flashloader system. Being a strong partner and user of VRTuned for years, we needed to see what the car could really do. Having tested on our dyno a 2010 Turbo PDK we were familiar with and where the baseline and ECU Flash tune would be approximately. Even though the Turbo S comes from the factory with 30 more horsepower, there is always more room to improve. Where VRTuned excels is specific tuning in the 1000’s of maps to make sure the entire RPM range gains safe and reliable horsepower. VRTuned had quoted a gain of going from 530bhp to 615bhp from just the flash. Though we usually feel these bhp numbers are high, we could only see what it did on the dyno. So to get good comparative test results, we did consecutive runs with about 5 minutes of cool down time in between. We ran the car first with the GIAC flash and then followed up with the VRTuned flash. Being on a Mustang AWD Dyno and having 91 octane as pump gas, the numbers were against us already. Typically the Mustang dyno has a 20-25% drivetrain loss. When running the Turbo in Sport Mode, the vehicles throttle response and low end torque is noticed on both the dyno and street, however based on EGT temps, Sport Mode can usually yield lower mid to top end power.
As a completely stock car, we did tests in both Standard and Sport Mode to show the difference in power gains. What we yielded was a peak of 541awhp and 534ft/lbs of torque with the VRTuned flash in Standard Mode. This car actually exceed the typically drivetrain loss showing that the VRTuned Flashed Turbo S was actually much stronger then expected. With Sport Mode on and an increase in boost pressure, the car spooled up quicker making peak torque at about 400rpm faster. However this then tapered off earlier as usual with cars in Sport Mode. Sport gave us a peak of 532awhp and 524ft/lbs of torque. Comparing to the GIAC tuned flash on the car running in Standard Mode for the best possible results, the car pulled consistent with VRTuned to about 4000 rpm where the tuning differences shined. From 4000rpm to 6800rpm, VRTuned kept a consistent gain over the GIAC flash of about 20hp. With a peak of 506awhp and 515ft/lbs of torque, it is clear that VRTuned’s tuning is far more in depth.
The best part of the ECU Flash from VRTuned, it was all done in about 20 minutes using a laptop and plugged into the OBDII port. No removing the ECU, dealing with scratching the interior, or having to wait for the power. Check out the pictures and video below. Vivid Racing and VRTuned flash all Porsche Models Here.
