Are all TCU tunes the same? Renntech vs Eurocharged vs PTG. I read the PTG was the best but I’m not sure if that’s verifiable. Seems like they would be similar. Was wondering if there are any differences between brands.

These tunes are basically computer codes so I won't be surprised to see similarities between them. So you'll always better off to trust the company and their support and integrity over the performance numbers.
