Enjoying this thread.

On my lean burn Talon I did some load base dyno tuning a few years ago and could never simulate the real world road conditions. It still amazes me how driving is a major factor to getting good FE. I have about ten different test roads with different traffic and terrain, with that said all have of them have different tuning maps.

IMO its just way to difficult to simulate actual road conditions on a dyno. In my case this applies to 20:1+ A/F on my car. I personally don't like being at 16:1 to 17:1 A/F, these A/F ratio's will make heat and I stay away from them. So my map goes from 14:1 to 20:1+ instantly.
