Jake Jenkins and his buddy Rod brought down a 04 F7 efi for me to use for the test. It was always a strong runner and we found the proof of that when it was dynoed. It had 145 hp stock. It was like it had one of the best 05 boxes on it. We added our BMP pipe mod and it made 150 hp. No other changes made. We then added a D&D y pipe and picked up another 1.5 to 2 hp

Here is a graph of the stock pipe and then our BMP pipe mod showing the additional 5 hp. I'll post the dyno sheets too.
