Update:

My son and I took the car out this afternoon for the test drive and was completely surprised how soft/smooth the low speed 2-3 shift now acts. I'm talking race car to grandma's mini van change!! This is at the lowest accel 2-3 shift in traffic and I even let off of the accel pedal right at the shift a couple of times and it was still smooooth!

The bad: At medium throttle 2-3 shift, it does flare up 1-200rpms at the shift. I did not try a WOT hit due to this flare.

This change was from the TF-2 (no orifice plug, higher than the TF-2 throttle pressure) to only adding the .086" plug. This single change was amazing on how much the 2-3 shift can be tweaked.

I have the car cooling off and I will be pulling the pan first thing in the morning for another plug change. Where do I go from here?

I have the following drill bits on hand:
.092", .094", .098", .099", .101", .106", .109", .110", & a .120".

What is the next test? I am thinking of swapping out the .086" for the .098"-.101". I'm just not sure how much this .012"-.015" change would affect it.

Thanks everyone!! This was very cool test up
