2020 WRX stage 2 93 tune. Started adding a bottle of this to my tank at my tuners request (he runs it in his personal 2019 WRX) and it really made a noticeable difference in everyday driving. Engine is running smoother now, idle through whole rpm range, not getting any mis or really “hesitation” that it had been getting off straight 93 pump gas. AF learn was out of spec: +/- 18-20%: in half a tank running this product those numbers have dialed in and are staying under +/- 8% where they should. Highly recommend this product if you’re running a similar set up! I have noticed throttle response is more accurate, it feels like the car is running at its best, and the car just feels “happier,” I guess would be the best way to explain it.
I use this in my 2012 Cadillac CTS-V, 6.2L, Supercharged Motor. Friday nights here are big for Street Racing. I'm a 64 y.o., gearhead, so when I pull up in the Caddy, I get some raised eyebrows. I always use, non-E-85, premium fuel and dump a bottle of the go-juice in the tank at the beginning of the evening. It is noticeable in the seat of the pants feel from the stock 556 h.p. LSA.
We race everything from hopped up diesel trucks (yes, this IS Montana!), to 5.0 Mustangs to JDM projects. I'm not saying I beat the 'stangs all the time, but enough of the time to get some notice and respect.
Yes, I would recommend this to a friend.

Like the octane boost although the contents do not drain well norm the bottle. Something in the design of my truck gas filler port prevents the bottle from emptying. No doubt as an antisyphon mechanism.
