Hi,

I am in the process of purchasing a 2007 Suburban 2WD with the 5300 that has the Flex Fuel option and (I am assuming) AFM, I am not sure which 5300 engine is in it but I read somewhere
if the 8th digit in the VIN code is '0' (which mine is) then it is the Iron Block model and I do know the the specs say 320HP and 340 Torque.

The vehicle is a one owner that has been in California since new and is in great shape with 17K miles and seems to have every option but Navigation.

Before I delivery of this vehicle, I had heard there have been several software updates put out for the AFM to make it smoother and would like the dealer to do this before I sign on the dotted line.

Could anyone list what I should ask him to do?

Lance.
