Interesting. May be worth a shot. I though I may have been feeding one side when I added that sea foam stuff, but didn't do much past that. The equalizer tube,...is that for boost only, or is it for vacuum also? If so, then I did get both sides, but definitely more on the driver side. I'll buy more of the stuff and run it through the fuel system, then try running that crap into a vacuum hose on the passenger side.
