I've had max throttle at 32 TPS however in many situations I found the limit more like 30, and at lower rpms the limit was about 28 and I think sometimes even lower than that.

So I switched to using Load (LOD gauge on my ScanGauge) to manage Lean Burn. The limit stays right around 90, which I think is percent. Occasionally I will lose Lean Burn below 90 Load but it's a pretty good way to judge - in my experience. Better than TPS.

As you gain or lose speed with TPS held steady, Load will increase or decrease. But the limit of approx 90 stays pretty consistent. You get to step into the pedal deeper (or have to lift your foot some) depending on those Load changes, but at least you can see the change happening on the gauge. If using only TPS, the limit number changes but only experience tells you what the limit is at any given rpm. that's why I use Load now.

Yesterday I was able to free up one position on the gauge, so I can see Load and TPS simultaneously. I haven't had enough time behind the wheel since the change yet, but eventually I might get an idea of how the two readings can be used together to manage Lean Burn.
