Porsche 997 Turbo Dyno Tested with Great Results VRTuned.com February 25, 2011 Company News We had a local 997 Turbo customer that came up to the dyno to run his car. Equipped with the Fabspeed exhaust and headers, we added our ECU Flash for him. The car put down an impressive 477awhp on 91octane and 532ft/lbs of torque on the best of 2 runs. Typically, our Mustang Dyno baselines a 997TT 6speed at about 370awhp. So the results are good showing 100HP gain with flash and exhaust.
