Hey guys I am a newbie to the STI world and have started to mod. I will be installing a Cobb 3" catback and APS 65mm cold air intake this week. I won't be getting my Cobb downpipe and tune until the first week of September. Is is safe to drive with the catback and cai without a tune or will this create a lean condition?

Thanks for the help!

get a dp, Ap and a protune, and you'll be set

The stock ecu adapts very well to changes of that magnitude...so yes, like everyone said, you will be fine.

will stage one make any more difference with a CAI and catback than it will Stock?
Probably not. But Stage 1 is great on its own merits. If your stock now, your turbo spools like a fat slug compared to Stage 1. It's that much of an improvement.
