Bummer, took Hope to the dyno with the duals and lost power. We lost 1.5hp and 2.9 torque. I'm going to do a few things then try to make it back to the dyno see if we can get it back. Dyno guy thought I had too much exhaust for a 460cc. Funny the duals I built for my 495 gained power everywhere LOL.
What did changing to the big exhaust do to your AFR?
