I think for sure you do not want to be spraying
through the shifts. If you confine the shot to hit
after the clutches have settled, and work on the
trans settings to be proper with whatever new
line pressure you end up at, you should at least
get reasonable service life. Just expect that
stress accelerates wear and raises probability of
failure.
I have the impression a lot of people run that much
added HP and survive for the short term. But, it's
also a very effective way to find any weak links in
the drivetrain. Especially if you jump in with more
enthusiasm than method.
A shift kit with some moderate increase in pressure
but focusing more on improving the cycling of it
is probably a good idea. I wouldn't go stacking every
washer in the kit and brute force it, you would benefit
from doing some transmission speific tuning after the
install to make the most of the mechanical changes
Also if you're getting a shop install, I think you'd be
well off to have the line pressures read and checked
against sensible limits (but I don't have those, get
them out of the Helm books or from some other good
reference). That's a good thing to do for a driveway
install too but most people don't have that gauge or
test procedure.
You should attach your mod list in your UserCP>Signature
so people have a better idea of the car.

I have a H/C car that I had to take my stage 3 shift kit out of. The tranny shop wouldn't warranty their work if I left it in there. Now it shifts better and seems to be firmer.
