Need some tuning understanding
I don't really know that much about tuning a car, I've been reading up about uprev and ecutek here but there a few things I don't understand. So first; if I want to get my car tuned do I have to prepare it in anyway? Do I buy the tuning software and cable and then get a tuner to do it? Do I just take it to a place that tunes it? Is that the same as a etune?
