People will tell you otherwise but after experiencing both I feel the difference is marginal.
I have done ECU tune, full exhaust and intake tube -- my car sounds great now but performance-wise the changes were minimal. I am extremely skeptical to the massive gains I see on these charts for our NA cars.
