Dyno tests were performed under strict controlled conditions on an independent Dyno Dynamics machine in order to show a true and realistic result. The test car was a 100% stock 2012 DCT with 62,000 miles. A healthy and genuine increase of 10-12hp | 8-10 lb/ft from 6000-8300rpm. The results shown are the highest stock result vs the highest result with the intake.  This can be clearly seen from the shape of the stock dyno run as its shape is smooth and the power does not fall off at the high rpm.  The stock car makes its peak power at the factory 8300rpm.

Many companies will use stock runs which are early runs in the session with high IATs which result in the ECU retarding ignition timing.  This results in a graph which does not have a natural shape and flattens off at high rpm.  More importantly, the upgraded airbox dyno graph does not have a torque curve which has a consistent gain through the rpm range.  These types of dyno results suggest a correction factor has been used to show a false gain.  The test performed here shows a realistic result as the torque curve is almost identical at low rpm and only begins to gain power after 4000rpm and especially after 6000rpm where the air demand is higher. With modified cars with exhausts which delete the highly restrictive primary catalytic converters, the results will be similar or higher.
