Yes. Quick and soft. Keep line pressure close to stock and decrease shift time. And use a ton of torque management during shifts. Sorry, I thought that was obvious.

And still doing it... Close to stock? Decrease shift time? To what? What levels are safe?
Yes, the info is available, but you've got to dig for it. But you opened the door by suggesting to do something, then leave no info., lol
Not everyone who comes seeking info has been doing this for a decade... Much information is lost anymore! Assume the question is legit and provide guidance, not just statements. Is the way things were when the site was very helpful to any who asked. I'm not sure or I would answer...
It's going to depend on the car and how much power it makes.
Leave shift pressure stock unless you are having problems completing the shift.
Decrease shift timing to as low as the tuner will let you, if you'd like.
The timing pulled between each shift is going to depend on the power the car makes and the parts inside the transmission.
Look at a tune file, for example shift times.
If the factory shift time was .400 seconds, a little bit is .050 to .100 removed to make it around .300. Going alot would be decreasing it by half or more. Play with it too, don't take everything off the internet as the bible to go by. If you truely don't know sometimes it's a matter of trial and error but just know that error could make something go wrong. I tested crap all the time and went with it, if I didn't like it I dialed it back to where I thought something was safer.
Same with the close to stock comment, if you looked at the shift pressure you'd know where the numbers start. It's always either a matter of preference or how the vehicle can react to the change. Going 50% higher is not close to stock but 5-15% higher is. It's not always ideal to give EXACT number or information when not every vehicle can like the same things. Past that it again comes down to play with the tune, making changes here and there to see how it goes.
Bingo. No car is the same, hence why it's hard for me to post an exact table. I doubt any car I've tuned has the same tables.
Some advice is better than no advice
I just hope I don't wreck ****. I really wanted to use Overkill as a baseline, but Will just doesn't respond. It's bad when you do a web search for someone and a bunch of the results are to forums where people can't get a hold of him.
What year is your car?
Really good info. My car doesn't have performance shift. Might the perf shift settings be available on the PCM? I read something about perf shift being the default after a certain year, but I don't know if that's true. I would think that I'd at least want the shift pressures and timings that perf shift used, but I could be wrong.
I think I have an overkill tune saved from a 98 or 99 gtp. I can email it to you if you want to send me your email.
I don't think it does that, from what I've seen. ^^
It may be tonight before I can get to my laptop and look for the tune to send you.
in dhp i can change its debounce and switch type, its got perf shift you just cant see it like dhp can. like i can turn it on and you wire in the switch to the pcm and now you have the button. other wise it goes into perf shift mode all on its own if your car dont have the button.
I have dhp. I've never seen it go inot performance mode without actually wiring in the switch and making the changes in the tune.
you wont see it go into perf shift mode, but it does.
pretty sure if you set the perf shift folders shift rpm higher it would hit that rpm wot.
ive set the perf shift higher in my tune but ive got a button.
I'm 99% confident the PCM never uses the Performance Shift tables without pin 21 being grounded (i.e. the 97-00 button).
That's been my experience as well. I usually don't change the performance tables on 01+ cars.
