Got my AFR gauge in and was able to make a few passes. At some point I will try to do some data logging, but for now it is iphone video. It seems I am lean at idle and it moving to a lean condition up top, but I am unsure what exactly I need to be shooting for at each segment. I have read the high 12 low 13 is ideal for WOT but again just looking for input. This is one of best passes the car has made, but it is after I fixed my valve train issues so it may not be a good apple to apple comparison. The plugs look reasonable. These early season passes are the best air we get, 60 degrees and high 20's humidity. My first inclination is just fatten up the idle, then either move the main jets it up or fatten up the high speed air bleeds. Again, just looking for numbers I need to be aiming at.
