Curious question, i know that some cars have a performance mode button, and can switch between the two, and hp tuners can tune for both of them, but can you add this to say like a base model impala that doesn't have it. Im pretty sure you can write for a performance mode and normal, but can you add the switch button and so fourth for the base

From what I've experienced those perf. buttons only make the shifts firmer. I have on my Saturn and my friend has one on his Camry.

true still something nice to have though, cause when just casually driving you can have the one tune easier on transmission and better mpg and then when doing something that requires performance you have it

Yeah you can, it's pretty easy, I've recently done it, I followed the how to on grandprixforums.net. It effects several trans tables, I added it because I do a lot of old man driving for.

I believe you need a DHP PCM (HP Tuners may be able to do it as well) to enable the Perf Shift mode in the PCM

Hptuners has tables for Normal and Performance shifting. I'm just copying the performance tables into the normal tables and calling it a day. Will @ overkill did this and even when I wasn't driving it hard the shifts were smooth and crisp.

Yeah, you def need a tuner, maybe I'll post tonight about my install, I wouldn't say that it's something that is needed but it's nice for me to be able to swich because I drve a lot dor work and put put around like an old dude.

Here's the how to at GPF with Pics, pretty good write up except I have no idea how he used 12 gage wire, I bought it at first, but it was way too huge, I either went with 16 or 18, I'll post a pic or two later.

From experience, I didn't notice any difference in mpg between normal and performance shift modes. I say anyone that wants it should just copy the performance settings into the normal shift tables and call it a day. Most off the shelf pcms are already set up that way anyways. If you've got a tuned pcm and you want performance shift mode because you want to save on mpg, you should just stop modding all together.

The one thing I remember for sure about performance shift mode is that it increased the max rev per gear by 200 rpm.

I'd just leave it on since the higher pressure and more crisp shifts mean less clutch wear.

That's tune dependent. You can change the shift points to whatever you want.

My stock tune has the same values for Normal and Performance tables, the exception being a slightly faster normal throttle shift speed.
