Even a stock filtered c5 z06 will benefit from a tune, so if you make changes even say a kn filter in place of the stock filter a tune would be advised. There are mail order options if you don't want to spend the money for a local dyno tune. If you want to monitor how much you car is trying to compensate from any cai or air filter mod get the torque andriod app and a blue tooth odb2 module and look at the short and long term fuel trims.

The supporting vendors of this forum imo offer a fair deal for a mail order tune for simple modifications like a cai, all you do is send in your ecu and they send it back tuned.
