Is there a need to be worried that it has this particular CAI and no tune?3
Hopefully I will be a ZL1 owner by next weekend!!!
Thank you,

It won't hurt the vehicle being untuned, the CPU can self adjust for up to +30% air flow and the maximum possible with a Cold Air Inductions CAI is 15-25%. The car will run with decreased MPG however, usually by ~10% (though +15-25 hp/tq).
Get under the vehicle on the drivers side and check to see if the prior owner installed an air scoop. This modification requires cutting pieces out of the vehicle and possibly a washer bottle relocation.
I would make sure the paperwork states this is a modified/altered vehicle and/or that there is an aftermarket air intake on the vehicle, especially if the vehicle is a CPO.
Without question, you would want to have the vehicle taken to an independent local tuner and have the engine read by a reader to pull current and historical codes and to verify the tune. Any local professional tuner; Mayham, RPM, JHR, PCM, Tick, Sinster would do. Expect to pay for their service before you buy the vehicle or, don't have it inspected prior to and simply budget $500 out of your purchase price and pay for a tune afterward. If their asking price is too high, all would be a good discussion and cause to drop your offer price by $500.
