I have a TVS powered 12 GT that is cutting out at 127-128 MPH. I need someone to guide me on how to post the .CSV SCT log and need some advice on what you think is going on.

Cutting out? Who's the tuner? What's the gearing? What is the rear tire size? What are the RPM limiters set to?
You could use dropbox to upload the csv and link to it here.

Or you can send to shawn at aed I'm sure he can tell you exactly whats wrong and fix it for ya!

All previous gears shift at 7300-7400, at 128 it cuts-out at 6900.

Let me see if this works. I am not going to throw any tuners name out for now. I e-mailed them a few days ago with no answer yet. That's when I turned to the forum for help.

And just the WOT part.

Just took a look.
For one, it looks like you MAF curve is very wrong. Your STFT is trying to add MAX fuel in part of the WOT run.
What Fuel are you running? Your Commanded fueling is a little leaner than I like to see. Your Long Term Fuel trims are good, so it does not look like any sort of vacuum leak.
Are you running E85 on a 93 octane tune?

WOW, you're car is trying to add 25%+ fuel and its still LEAN!!! .87-.88 measured A/F with boost... you need to stop going into boost! It is calling for .82 a/f's and running .88. Yikes
When it cuts out, you're still showing WOT and consistent timing (19'ish*), but all of a sudden it commands 1.20 A/F's... I wonder why

Check the name of the tune file. My first tuner sent me my initial tune file, and just looking at the name of it I could tell he had it set for the wrong intake. Right in the name it said "80-90mmstockairboxxxxxxxxxx", and I had the JLT.
Do not drive this car anymore at WOT! Quite honestly, I'm not sure how it survived this long. That's a lot of timing for that lambda and the knock sensor isn't picking up any activity??? Your tuner needs to adjust your fueling and maf curves.
I am running E-85 and the plugs are supposed to be NGK 6510's with 25K on them, unknown gap.
I have a new set that will be going in this weekend at .032.
The car is new to me so I am trying to pickup where the previous owner left off. The name of the tune has JLT 127mm, my car has the plastic 123mm so I am not sure if this will make enough of a difference. I was going to re-install the tune one more time just in case it didn't load properly. Also it has issues staying alive in D at very low speeds (parking lots). To cure this I bumped the idle to 750 but it's still not stable. And when coming to a stop at the stop light it usualy tryes to stall than jumps up to 1200+ than settles back down.
I was thinking the MAF or the injectors are not properly setup.

I agree, that log file does not look good. Wait to hear back from the tuner before you do any more pulls. Are you running a BAP or aftermarket fuel system?

The plugs were gaped at .040.
BAP, E85 and ID1000 injectors
I had the same exact question when I got my tune. I asked and was told that it is not enough of a difference to matter.
I was told stock lines are too small for E85... Even with a BAP
I don't think the lines are the issue. I think the tune is all jacked up, and still no answer from the tuner.
