Nah, going with the higher octane additives such as 104 or 106 won't do anything noticeable unless you've done mod's to where your cars begging for it. It's not bad to do every few months just to clean your injections, but for adding horsepower, you won't get any. The LT1 calls for 91 or 92, stick to that.
