. I only got info from one pass as my trigger switch was messing up. I gained about 6 degrees during that pass and was reading 5-5.5 on the O2. I have an 850 alcohol card with 150 jets all around. I am going to try leaning it out some more if all checks out ok. A couple of plugs were wet when I checked hem last night. This thing came alive about 1000 foot like it cleaned the plugs. If all looks well I will pull the oil pan and install a HV pump
