Thinking about getting into learning about tuning myself, I think it would be a fun challenge, and I was thinking about picking up a TwEECer RT. I was wondering if it would be worth it on a car with my mods and unknown future mods for the car. Or would I be better off keeping the money? I think it would be fun, but at the same time would like to see some gains once I got the hang of it. Thanks.
