Gauges look great. I'm looking at the same boost gauge as you, that goes to 15 psi. I'd really love to see your A/FR under boost. Did you ever get a chance to look at your fuel trims via scangauge? If/when you do, could you snap a pic of your STFT and LTFT at idle and, say, around 3K rpm? I think I have an identical setup to you with regard to PCV and breather, but my trims are really out of whack. I'll continue to check my hose connections. I hope that the lean condition and compensation fuel is due to the different charge piping and the MAF not yet being clamped by the FIC, but this is pure supposition on my part.I don't have a video as it's hard to do while driving but here is a picture. :smile: This is very similar to a video on level steady cruising as they don't move much in that case.
