That's a challenge, I'd like to see it done though. Good luck
I did a 13.1 on my first run. Left line at only 1,500 rpm. Can't get 3/10's with test pipes & an Osiris tune????

What else would it do? It's an auto, it shifts at the redline or damn close to it. You move the redline, it shifts at that red line.
That makes it real simple If it's a fact.....

You probably didn't see my post about me putting in my old 350z pumpkin w LSD & 3:90 gears. That was done on thurs, Friday I went racing The car pulled like a M Fvcker. One run was at almost 108 mph.

Shifted into 5th gear before the finish line, so another benefit of raising shifting point would be NOT getting into 5th gear. Another e/t gain

Seen those posts like 100 times.
Changing the gearing will obviously be best bang for the buck for drag racing. Maybe equal with running slicks. So I cannot compare those times taking into account the other times. It's just not apples to apples

I was looking at the bolt on times. Except for the top two, there's no reason, NO CHANCE I can't do the times of the others.

Rev limit can be raised with Uprev. You can then manually shift via paddles or stick up to that RPM without fuel cut or automatic upshift. I'm not 100% certain that raising the rev limit also raises the shift points at WOT... you really shouldn't raise it higher than 7800; I believe OEM is 7500.

If you mean changing the shift schedule in "D", unfortunately, I don't think there's a way with Uprev -- possibly ECUtek can do it.

However, you CAN raise the line pressure with Uprev, meaning faster and firmer shifts.

Thanks^^^^^If that's true, I'll ask my tuner to do that.
I admit not knowing much about today's cars & how they work. It's my age I don't even want to change my own oil. I do know a bit about drag racing & having mods work together, as apposed to just "the more the better".

Before the recent drag racing of my Z's, I drag raced a bit a long, long time ago with a 1966 Pontiac G.T.O. Long, long ago That's when I learned how to shift & about balance/working together when it comes to mods.

More recently with my 08 Z. I didn't just buy slicks for that car & do well, it took me 8 months to learn how to really use them

So, I'm a nice guy but tend to post "snappy" responses. Probably due to my age(little patience) & trying to have some fun. Nice, nice all the time is BORING

Raising the shift points is probably possible by tweaking the TCM. It would appear that no one responding to this thread knows much about tweaking TCMs (the hi-po guys usually go with a manual). I suggest finding some hi-po auto transmission shops/sites and asking there. Let us know what you find out.

Maybe a call to GTM, since they build upgraded autos?
