Haven't used it in my 991.2 GT3 but I've used it in my Z06. Mixed both Race Gas and Torco Race Fuel Additive to bring it up to 93 octane. Mix with gas to get as high as 104 octane. Works really well with more power and improved throttle response and is safe for cats. Using octane boosters, power gained is only what the tune was designed for. In other words, you can't get more power just using high octane gas, you're getting power which was lost due to poor gas. There are a lot of octane boosters which don't do much at all, so a word to the wise.
I only use 93 at the pump but I like to add 5 gallons of Sunoco 260 GTX from time to time. Added this one before the car got put away for the winter. Sorry for the potato pic.
I just did 2-year spark plug change on my .2 3RS. They looked great. Shop said my car was in amazing condition, especially compared to other GT cars they work on with similar mileage/track use. All I use is some 91 octane (either Chevron or Shell) and Sunoco SS100 mix to bring it up to 93. Octane boosters are garbage.
Orange Deposits are common all these octane boosters with MMT. Please stop using these octane boosters, your 10HP gain is not worth it! Your destroying your Cats and plugs!
