I'm looking into getting an official CAI. I currently have the Blackwing intake tube from the TB to the stock air box. And I have a K&N air filter in the air box. Of all the CAIs out there I am leaning towards the Vararam. I would like to get the tune version but I'm wondering if there is any significant difference between the tune and non-tune version. I can get a custom tune written but I'd have to drive it 150 miles first. And I don't want a CEL to pop up during that time. So what do you guys think? Tune version? Non-tune version? BTW, I'm not doing a cam or anything. Maybe a ported intake manifold in the future...
