I was thinking about getting a tank of this fuel, besides the damage to my wallet, you think I would see any increase/decrease in performance from my N/A engine? All I have is a Magnaflow catback exhaust. Only really drive the car on weekends, not for commuting. Thanks.

 

Nope.
There would be little or no benefit in getting 100 octane.
Save the $

 

Most ECUs don't recognize anything over 91 octane anyhow. Because that's the highest there is in most parts of the country though I get 93 when I fill up because that's what they have here in Long Island.
