TORNATIC!!

I have a '04 GTO A4 with a Predator tune. Yesterday on the 1-2 and 2-3 shift she started bouncing off the rev limiter so I had to back off so she could short shift.

When I took the predator tune out and put her back to stock she shifted fine in every gear. I put the Predator tune back in and she started bouncing off the limiter again!! Anybody experience this or know what the problem might be?? I've had the Predator for nearly a year now and haven't had any problems.

I'm not familiar with the mods that the tune is making.

Are you saying that you've run the same Predator tune for quite a while?

I trust you are experiencing problems only at WOT?

I would have to see the shift tables to better understand your issues. If you could find those and get them to me in a format I can use I would be happy to look into it for you.

I am not aware of any of our clients running the Predator tunes.

I talked to the people at my local performance shop and they said it has to do with the hot weather. They told me to raise the "rev limit" to 6400 and raise the "upshift rpm" to 6100-6200. I did that and now she's shifting fine. I didn't know the "Predator" needed a different tune for the summer.

The rev limit was orginally at 6189 in each gear and they said that was too low and in the heat she'll want to go past that.

Well good!

Looks like we both learned something. I understand what Predator is doing now.

Thanks for the feedback.
