Shelby

I have a 12' base model with FI high flow cats and catback.
I'm planning on putting some drop in k&n filters and that's it.

I want to get a tune but I'm not exactly sure where to start.
I see a lot of people use uprev.
But it looks like I need a dyno?

My boyfriend knows a lot more about this than I do, but his Damn pick up truck is faster than my car right now! So I need to step up my game lol.

Thanks guys
