I just purchased a 2007 Saab aero. I wanna get more performance out of it but I don’t know what I should do first. I don’t know too much about cars so I wanna be sure I do things in the right order. Any suggestions? I was thinking a cold air intake and a tune but I don’t know what the internals are rated for... anyone out there wanna inform me on what this car is really capable of and if a tune would be too hard on it without changing anything under the hood?
