700R4 TV setup and pressures (TV Made EZ)

Well, I have put about 3000 miles on this rebuilt 700R4 in my 72 burb since installation and my paranoia got the better of me, so I bought and installed the TV Made EZ system from Bowtie overdrives. (this is not one of their trannys).

So I installed the system at the carb, and also the plunger spring in the tranny (dropped the pan, pulled the old one out and popped this one in).
Set it all up per the instructions on the website (printed out and included in the box). All pretty simple. Hooked up my pressure gauge and took all the pressures per their procedure. Called them this morning to check that the pressures were good and thought I would post them here as when I searched I could not find anything concrete. So here goes:
(my tranny is a stock rebuild (stage1), with just some strength upgrades):
Also checked that I got a pressure spike with a tug on the cable and that I was getting WOT at the carb when pedal was depressed.
Transmission pressure at idle with TV cable connected:
Park - 75psi
Rev - 120psi
Neu - 75psi
OD - 75psi
3rd - 75psi
2nd - 180psi
1st - 180psi

Transmission pressure at idle with TV cable Disconnected:
Park - 140psi
Rev - 220psi
Neu - 140psi
OD - 140psi
3rd - 140psi
2nd - 180psi
1st - 180psi

Transmission pressure at high idle (1500rpm) with TV cable pulled:
Park - 150psi
Rev - 240psi
Neu - 140psi
OD - 145psi
3rd - 155psi
2nd - 180psi
1st - 180psi

I haven't driven it yet, but plan to this afternoon. Hope this helps someone who doesn't have access to a tranny guy.
