Tuned a V8 Panamera 4S with Great Results
With our already successful Panamera Turbo ECU flash, we just finished the tuning of a 2011 Panamera V8 4s. The V8 is still a strong engine for the large Porsche sedan and doing a ECU flash can really take advantage of some missing performance. Testing on our Mustang AWD dyno, the car put down 288hp and 296ft/lbs of torque. The Mustang Dyno typically has a 20-25% drivetrain loss from the crank horsepower numbers. Coming from the factory with 400bhp, this puts us pretty on point considering we also use 91octane. The Panamera Siemens ECU cannot be flashed via the OBDII port so it must be removed and sent in to be flashed.
Like other normally aspirated cars, the ECU flash improves throttle response, mid range performance from 3600rpm to 5000rpm, and stronger top end to redline. The peak HP gain at the top end RPM before the test stopped was 19 horsepower and had a torque increase of 7ft/lbs. However from about 4400 rpm to 6200 rpm the torque gain was about 12.5ft/lbs. A big help to the curve was with the addition of the new Agency Power cold air intake kit. The intake took out the huge dip that the Panamera experienced from 2500 to 3600 rpm. The intake and the flash gave the Panamera a gain of 50ft/lbs of torque at 3200rpm! We also gained about 40 horsepower in this area. This all equates to a much stronger V8 off the line.
Check out the dyno video (panamerac4sdyno) as it revs through the RPM and let us know your thoughts!

Cool, I'm thinking about it as well. Let us know how the removal of the ECU goes. That's my only concern.

My car is in the body shop rock fell out of truck on highway I was behind truck cracked lower front bumper (and some other small stuff), figured it was a good time to have the sport design kit put on. I probably will not have it back for another couple weeks. Turned out to be costly with the Panamera gone my other Porsche still waiting for the roads to warm left me with no sporty car, so I started looking at the deals on the Abarth's. I should have known better!
