I seem to only see the gauge read lean on decel at very low rpm (around 1500 and below), anything higher and it will go very rich on decel.

in the little box for decel fuel my settings are:
Fuel off above RPM: 2000 RPM
Fuel off below load: -12.06 PSIg
Fuel off below TPS: 1.95 %
Fuel off Coolant min: 30 degrees F

I may have just answered my own question when I saw the TPS was labeled in percentage and not voltage.

I did a quick check with the calculator and 1.95% is like .08775 volts (assuming 4.5 is the maximum which it is pretty close to that).

Can I raise that percentage up to say, 15%? Because I've watched on the computer with the car running, sometimes the closed throttle voltage will vary a bit, and go higher than .08 volts (like up to .45 volts once if I recall correctly (I may have done a TPS reset then)).
