I've been trying really hard to get the software update Powerchip made for me buts it's been rather difficult. They keep saying they're busy, but all they have to do is email a file to a vendor in Los Gatos. But anyway, here's a link to my thread: http://www.e90post.com/forums/showthread.php?t=372973
Oh and by the way, I had the tune loaded before the manifold was installed. It ran fine. It just had some weird gaps in power.
Interesting.. keep us posted!
