Hi Gents,

I've installed this a few weeks ago with no luck. The longest I was able to go without a CEL was 600 miles, after the initial install. Ever since then, I can only get to about 60-90 miles before getting a CEL (always running lean). I've tried it at nearly every setting.

I think I know why but figured I'd ask first. Does this not work for HFCs? I'm thinking any setting, even at its lowest, is too strong for HFCs, which is why my codes are stating I'm running lean.

Second question, is there a fix for HFCs out there? I've tried foulers, didn't last 50 miles...
