New member looking for some input on tune

[izcain]

Hi guys,
So I have been studying and reading thru here (Reading the trans tutorial, reviewing older posts) and I was wondering if I could get your guys opinion on this tune and will be a safe bet to start with on the 04 GMC Denali out in the garage. Just looking to firm up the shifts for starters and wanted to get opinions before flashing it as I dont want to hurt anything.

I removed 50 percent of the tm and upped the pressure 10% and shortened the shift times to .250........ Right now without this tune the shift is very lazy. Has a fresh trans in it and I would like it to last!

I wanted to work on this first then start tweaking the engine settings.

Thanks for any input guys!

So the vehicle is otherwise stock (mechanically)...?

[izcain]

Yes it is stock right now.

[izcain]

Would I be better to do something else instead since it is stock?

Just looking to have firm positive shifts nothing gear banging. Was also planning on installing the corvette servo also for a little bit more.

Thought I would start here before changing anything.

[joecar]

I'm still looking at it.

[izcain]

No problem, thank you for taking a look!

Just trying to learn.

[izcain]

Just wanted to check in and see if anyone had a chance to take a look and if what I am doing is going in the right direction.

[joecar]

I'm slowly taking a look (I got family in the hospital so we've been spending most of our time there)...

I'll take a closer look today (sorry it's taking so long).

[izcain]

I'm sorry to hear that! I hope they will be doing better! Family is the most important thing!

I'm making various edits to your tune file (shift, pressure, shift time, PE Enable...)...

you will need to install the latest software (to open .ctz files): Update-Oct-28-2014

I'm editing your WOT shift points because they are upside-down...
