Huge Increase in Power

By the way, this really is an amazing product. This is the second time I’ve run a full cleaning in my ’01 Saturn SL2 (203,000 miles), and I can tell the difference after just 400 miles. Huge increase in power, and the engine doesn’t sound like it’s wheezing for life when I step hard on the gas. I may be crazy, but it seems to me that I’m getting the same power output as I did before adding Auto-Rx at lower RPMs. Normally, I have to take her up to 4,000 RPMs or so to climb some of the hills in eastern Tennessee/western North Carolina, and now she’s climbing without a complaint at 3,500 RPMs or so. Thanks.
