So i have installed the Riva Stage 1+ kit and the Can doo pro , with a half a tank of fuel , my weight 218, the is smooth running and arm wrenching acceleration but is only reading 65 mph , any ideas because after 2000 bucks all i got was a loss of 5 mph, the machine only has 3 hrs???
Mine is the same,let me know what you find out?
The hose on the manifold! The J pipe wasn’t on all the way . Also the hose clamp on the blow off valve was lose.
