Default Question about autotune

Hey guys I put in my autotune today and my friend said that I need to go in and block off the clean air system for my bike so that the o2 sensor will get an accurate reading. When I took my bike on the highway today after installing the autotune the bike engine shut off evertime i hit the throttle hard which leaves me to believe that my friend is right. Just wanted to know if any one has dealt with this before or if it is something else wrong with bike

Yep, that's exactly what you need to do. I just finished reading a similar post on another forum (was that you?) where the Dynojet rep said to do that.

That is correct you either need to block off or remove the PAIR system. The PAIR system injects fresh air into the exhaust. The oxygen sensor reads this and thinks that the bike is running lean and tells the autotune to add more fuel. The PAIR system doesn't allow the oxygen sensor to get a proper reading so it must be blocked off or removed.
