thats not correct.

the chip has nothing to do with the turbo.
if you have a big or a small blower the only thing different will be back pressure, boost temp and lag.
the only air information the chip gets is boost pressure, given by the MAP sensor and the air temprature.

a drop in boost temp caused by the increased A/R og the bigger turbo might cause your car to lean out at high rpm/boost if you already are on the limit of your injectors...
