Default Help problem with lean DTCs

I have been getting lean DTCs with a chipped ECU, I reinstalled the stock unit to take it to the dealer and it won't throw the codes again, switched back and forth and it will do it with the chipped unit not with stock.
Could the MAF be bad but not enough to throw lean codes with stock boost?
