running too lean

[Mang213]

Need some help as to why Im getting the po171 'running too lean' code after my install of a Spectre cold air intake kit. The setup was originally designed for 99-06 trucks, but they ammended their fitment schedule to allow for the nnbs trucks, with modifications. I know WHY Im getting a lean code, but Im surprised to see this issue pop up on such a minor mod. Is this intake tube really allowing THAT much more air into the engine, and if so, what do I need to do to fix this quickly, before my motor burns up? Is it possible that I need a tune to get my a/f back to normal, or am I looking at injector or fuel sender upgrades? Ive rarely heard of this problem on a CAI install, but I understand why it could happen. Just seems like such a generic upgrade to pull a code like this, already.
Also, my truck ran kinda hot today in stop and go traffic. This truck has NEVER had a temp fluctuation before. Coolant temp jumped up to 220*, but when I cranked the heater it went right back down. Im afraid my motor is gonna fry if I dont get on top of this. Any suggestions?
