Um no, we benefit from 93 octane as well. The SS benefits more since it has seperate octane tables for 89 octane and 91/93 octane. For the SS, being on the 89 octane reduces power a lot! I actually beat an SS by .1 this past weekend because he was on the low octane table.

The v6 benefits since it can add more timing. The v6 will actually add timing until it detects knock and then it will back off. Using 93 octane allows the car to add timing and aids it to run a lot better.

Also OP, you have to remember that horsepower numbers don't stack up. If an intake is advertised as 15 hp and headers are advertised as 20 hp you don't get 35 hp from these both. You might end up with something like 20 - 25 hp. You probably should have picked up more than the 20 you did but also remember that things like the tb and the catback exhaust really have little to no gain in hp
