Testing Data:
Continuous dyno pulls and testing under the same conditions produce identical gains time after time. Even our hottest runs, Run 4 (197 degree starting temp), showed a 5 horsepower peak gain and 26 horsepower gain throughout the mid-range over the factory intake system.
Next, we uploaded KTuner's Stage 1 ECU map with the factory intake system and our High Volume Intake System. The coolest runs, Run 2, showed an 8-9 horsepower peak gain and 25 horsepower gain throughout the mid-range.
The hottest runs, Run 5, showed a 9 horsepower peak gain and 18 horsepower gain throughout the mid-range.
One of our main focuses with this intake system was to offer a factory-like fuel trims (much like our 1.5T Cobra CAI & SRI) for optimal drivability and performance. We spent quite a bit of time designing what we determined is the best intake system/MAF housing on the market. Thus far we have seen Short Term Fuel Trims within +2-4% of the factory. We have a few more tricks up our sleeve, but are very happy and confident with what we have currently.
