I hooked up a voltmeter to Vf1 & E1 pins in the diagnostic block. Once the car warms up the voltmeter reads 3.5v. So that looks normal. While cruising around it reads 5v (4.97) in all gears & all RPM ranges while not in boost. Anytime I touch the throttle it reads 5v wether I'm barely touching the throttle or WOT. It does this from off idle to 5000rpms off boost. I haven't look at what it's doing while under boost. I don't have my wideband hooked up yet so I don't know what my AFR's look like at the moment. So from what I understand i'm running lean and the stock ECU is trying to richen it up?
