Shelby GT500 RPM limiters

Hey,
I hope you're all doing well and in good health,

let's get to the point, I attached a Shelby GT500 file equipped with CAI only and it's something new to me to deal with ford platforms. the issue I have that I couldn't raise the RPM limit up to 8000 what ever I do it's still shifting at 7200 - 7500.
I tried to raise the limiters and other tables but with no benefit :doh:
these are the tables that I adjusted:

- Cutoff
- EOT
- Base
- TCM RPM limit
- TCM RPM limit 2

and still shifting at 7200 -7500.

any help to solve this issue would be much appreciated and TIA.

Any suggestions or ideas?

We tuned a few shifting nicely around 7800 no problemo.

Dumb question….i see you raised a bunch of limiters but did you raise the actual shift points?

I thought the TCM wasn't tuneable on these cars yet?

:shrug:
If you read carefully I mentioned that I tried many things with no benefit, and nothing changed.
even if I raised up the (actual shift point) it would not make any changes.

I dunno man, you didn't list the shift points in the first post in the list of tables that you adjusted. I opened the file and all the shift points are set to 7000-7450.

Don't mention it dude, I'll give it a shot this week to figure out what is happening.
