Razor you didn't but the guy working on it said to try it, There is no dyno close to here, He said let the water lean the engine out some and see what happens, I get no knock either way, It is a lot easier to get a system put on than to get it working, Thought about just putting it on my Grand National but it is running pretty sick right now, Took it out for a long drive and it went from running pretty good to every time you boost it just back fire, Pop and crack and slow down till you let off but this is not a GN thread so will get off that
