So, I could easily show my worst and best runs of the day, and without changing anything, show a 10 horsepower gain from doing "mod x".
Catless headers with relocated O2 sensors and secondary race cats (like HJS) will provide the most power gain without going forced induction.

Why then do a lot of tuners promise +20hp then if its not possible? Or they do a lot of dynos and pick the best one and "sell" that?
