How simple is it and how much do something like that cost?

 

[Dynotronics1]

cost is 459.00 and comes complete with everything you need!

Very easy to do. If you can turn on your laptop, you can load and log files

How would those changes affect smog?

Does the tune require premium fuel? Have any before and after dyno plots?
