Yep, the secret is out! 😀 The warranty issue is a real concern I’m most likely not going to mess with the computer settings. Thanks for your comments. Charlie F

Thank you for your advice I am seriously rethinking about installing one of these tuning modules.

Hi Birdman i just downsized from a 40’ SuperC with a 350 Cummins to a 25’ C on a Ford 450 with a V10. Times have changed and this better suits our needs. I just need to get used to the vast difference in engine performance and handling. Thanks for your comments.

I have to admit this has crossed my mind. Those are good points

No, speed is not the issue it’s the frequent downshifting when climbing I just think the shift points can be better adjusted.

Thanks to all for the replies I have something to think about

I’m curious about those software devices that are used to up-tune engine performance. Are they difficult to operate and which devices have people used?
