cai cause stock sled to run lean??

[lightening800]

i have a 13 m1100t with just the cai and mbrp can on it,and has 90.5 gr dalton weights right now with tan spring, its not overevving, i have a bd 2,0also but is getting reflashed, anyway when i hold it pinned from a dead stop or rolling then hit it after a second or 2 it almost cuts the motor out and if i look at my af guage its at 14.7 ish and my guage says lean so its actually lean>> shouldnt the factory ecu compensate with having a 02 sensor in exhaust for it being a bit lean?? i think it is trying because the more often i played with it full throttle, it seemed like it was trying to compensate.. non the less it sucks when you squeeze the throttle across a deep snow field and it rips for a second then falls on its face..wierd this is the first time it has done this, i had the 2,0 on for a bit but was programmed wrong and was very fat full throttle..any suggestions?? i know i can fix it with the bd box if it is lean but what about the stock symptoms?? thanks

Haven't seen a lean condition from cai, and there are plenty out there running around. Does it have the same symptoms from idle to wot if you roll on smoothly?

i was thinking and i think what was happening was it was starving for fuel, i had 2 bars on guage and it felt like it ran out of fuel when i would pin it..because earlier that evening it was fine..thats stupid if thats the case, cause i had lots of fuel if you go by the guage, that would suck doing a nice climb somewhere and it falls on its face cause of it not sucking the fuel from the back of the tank..

i dont think lack of fuel was the case, i filled it and it only took like 6 gallons so it wasent near empty yet..unless those stupid smart valves are having issues,,
