Default Lean hiccups while driving??

I was driving the car on the freeway and I notice a couple lean hiccups while cruising at a Constance speed of 70mph. It will go lean for a split second or two as I see it on my wideband reading lean and will return back to normal. Anyone know what can cause this all of a sudden.
Car is boosted on s300 and was recently tune about a month ago. The only problem I may think that may cause this is the gm iat. The iat is also brand new.
