I tested it both ways, and testing it with the vacuum line on is a real world test. It's the pressure the vehicle would actually see. When I accelerate and the vacuum drops, the pressure should increase. Not by a lot, but should increase. It shouldn't drop 6-8 psi. Anything that had the ability to datalog would have told me when I was going lean, which would have led me to where I am a lot sooner. My intention is to get a Motes set up here in the next couple of weeks (tied money up in a vehicle I am flipping)
All that aside, how is it this became some sort of ****ing contest? Your ability vs mine? Had I had access to data on this thing, I would have figured this out a while ago. I, unfortunately, don't have several hundred bucks to toss at a Motes considering I have spent the last year fixing the previous owners massive amounts of screw up.
