Doesn't run with CAI

I recently (today) put a BBK cold air intake on my 2010 V6 4.0 mustang. Everything connected fine, no problems with installation, but the second the car hits 1500rpm, it stalls and dies. I can't hear any vacuum leaks but I haven't looked yet. It's very consistently at 1500 which makes me doubt a vacuum leak. No check engine light or service light. Any ideas?

If you use an CAI without a tune you are asking the system to take in more air than the ECU expects and it will freak out. Best case is that you get engine rev issues. Worse case is that you run the engine lean, overheat and it's time to invest in making more money.
