Thanks for the reply, 61-63. I will weigh the air valves after I take the engine off the dyno. Unfortunately, just running out of time . But actually, it is acting like they may be a little too light based on the air/fuel ratio when I first load in the dyno. It goes pretty lean then catches up after a few seconds. I have talked to a couple friends that dyno lots of engines and they say AFB's response is pretty unpredictable on the dyno as there is no way to really duplicate the load of a moving car with the static load a dyno applies. Those air valves probably need to be tuned once back in the car and driving. They said Q-jets can present similar challenges but are soooo easy to tune compared to AFB's. I am planning to try and get a Go-Pro camera mounted above the secondaries to take some video of how the air valves are operating on the dyno. Just to see how they behave. 61-63, I will be in touch after running it again. Thanks.
