I had the compression issue after using the Altamont ave 112 Sunoco fuel in my car for the fisrt time. After the fuel was all gone, I noticed it was smoking less and seemed to gain some power back. I was also running the car rich, as I bumped up the fuel pressure 4psi when I installed the fuel system. I turned my fuel pressure back down to 58psi static and Sea Foamed the car yesterday. I did a leakdown test after work today. Zero loss on all cylinders at 160psi. Back in business! Have you ever run any MMT-based additives like Torco? My old motor failed a comp/leakdown test because of buildup on the valves like yours. I actually was running some of the rotterdam racegas back then too but we blamed it on the torco. --- _[View the full topic](https://forums.speedlife.net/t/new-track-wheels-and-slicks/243579)._
