Now tell me something I don't know.  |

Just what does the M stand for? By increasing your RPM's you are PUMPING MORE AIR THROUGH THE ENGINE EVERY MINUTE. Pump more air by increasing your RPM's and you defeat your lean burn experiment. That increased volume of air must be mixed with fuel. Run your engine at the same number of RPM's as before. Lean burn is not your problem. Your engine can't properly handle the changes you have made and produce the same amount of power. Your insistence upon maintaining the same performance level is unrealistic.
By the way, your increase in RPM's from 1500 to 1700 is a 13% increase. Did you know that?
Do you think that maybe it's impacting your results? So if you're pumping 13% more air, do you think you might be pumping 13% more fuel with it?
