Not sure on your logs as this is something Im still trying to learn and understand. But if you are curious about Cobbs release you can always look on their website or forums for updates as they come available.
I cleared my check engine light the other day and my A/F learning has been in the low single digits now. I get CEL P0420 and will be getting a downpipe soon to lose my bad cat and go stage 2. The pull was in third gear and I think my boost is pretty much right on for a 2007 stage 1 (Cobb target is ~13.5). I think I might try to track down a stock air box first though as I don't really want to ruin my engine for a noise maker.... Should the intake make me run rich because more air is getting in than the MAF picks up? I would think more air would tend to make it run lean.
If the SPT isn't much different than stock why would it require a tune? I still think I might try to trade my SPT for a stock air box. Since my car is my daily driver with 113,xxx miles on it I think that following the map's requirements to the "T" is probably worth it... With that being said anyone want to trade a stock air box for an SPT intake???
