I have codes p0171 and code p0299 could second code cause first code?

Yes, underboost will cause lean running conditions as the ECM cuts fuel to the engine. For the chevy cruze, the most common cause is a crack in the turbo housing/manifold, and the hotter the weather, the hotter the turbo, so the more boost pressure will leak. Speak with the dealer and see if there is a TSB that will cover the repair, since the turbocharger/manifold combo is over $600, and these turbos have failed many times.
