? On Changing Shift Points On Auto Trans

Looking for input on changing my shift points on 06 w/auto. With past handheld tuners I had (Superchips & Preditor) the canned tunes would stiffen up the shift points and make vehicle feel great. The new tunner I have has options for me to change the shift points. I admit I don't know diddly about doing this and want to do it safely. I guess I can change them by RPM's or speed. Can anyone help me out.
I will call manufacture later, but I'm hoping to get some input so I can ask better questions.
Thanks in advance.
PS Today I start year 2 with new heart. It has been a rough first year, but they've got me customed tunned much better now. I'm ready to play

Way back when, I had Doug set my shift points at 6250 rpm. Seemed to work OK for me.

I talked to the manufacture and got the answer I was after. I'll be hitting the dyno Thursday.
Thanks

Purposly leaving out manufacture to keep away the flaming that goes on. I am not doing custom tunes. I was really wanting firmer shifting out of my auto trans for the fun factor for around driving town. The canned tune in my flash tuner didn't do it. But I found out how to change the program and will try it out as soon as I run out the reg gas. Then after dyno test with and without tune I'll be glad to hopefully brag up my tuner for none racer, that's me. I just want more fun while driving, safely.

I've got the GMS Fuego. I have all Granatelli parts CAI, exhaust, strut braces and supension upgrages. I've been treated super by JR and his staff, and hate the flaming that goes on against them. To each there own. My performance and custumer service have been excelt with GMS.
I will post dyno results hopfully tomorrow.

I'm not flaming them. I was just wondering with tuning device you were using. You should be able to change the shift points just like the sct2
