This question comes up alot on my channel:

For you newbies who can't decide on going the ECU Flash/Tune route or a piggyback unit. My latest video addresses some things which might be useful to you. For owners who have tunes or piggyback units, I'd love to hear your input!

As always, thank you for supporting my channel guys.
