I just got my CAI in. Can I put it in without a tune or will something in the ecm be off? I am planning on sending off ecm/tcm next week for tuning, but I would like to put in on this weekend?

From what I understand, you'll be running lean at WOT. ECM needs to be corrected for this.

Yep, with a CAI you will be rich on the bottom and lean on the top (Chris from VMS direct words) without a tune.
