I agree that the rate of advance is critical to your engine's performance, but I would suggest that you wait until the converter change to do it since you already have the converter.

Once you put in the looser converter, the motor will become loaded after the advance is all in. So it is less important whether "all in" is at 2,500, 2,200, or 2,000. Right now, with the converter at 2,500 and the "all in" at 2,500, the engine is loading without full advance. Not ideal, to say the least.

If you were not going to change to a looser converter, then going for a quicker curve should be one of the first things to do. But now with the looser converter coming, I think it would be best to do the additional tuning with that combo.

Just my .
