Didn't know where to post this but been looking into possibly getting the tuning school courses for gen 4&5 and just wanted to ask if anyone was familiar and if worth the money as they are not cheap. I wish they went more into turbo applications like atsv/cts vsport and ats/camaro 2.0t as I am getting a lot more people interested in tuning these cars and just like to learn more on the platforms of the right way on certain things as a lot of times questions go unanswered on here on some more complex problems.
