Mine has Tyga pipes and a chopped airbox lid. Choping the lid made a differents to top end power on mine and it felt a bit more responsive. The standard lid only has peashooter holes that look to be smaller than the rest of the intake.

Has anyone checked to see what the powervalves are doing with the standard card, might be restricting power in the high gears by not fully opening them.

I advanced my 28 flywheel 2 degree's with a stepped woodruff key. This one is the protype thats 5 degree's.
