I misunderstood the question. I thought they wanted to know how to improve the otherwise poor reception.

edit - to clarify, I want to know the reason why the reception on an aftermarket unit is worse than stock, not have someone tell me that I need to buy an antenna booster.

I've already searched. And I still have the same question as the OP. And it's not related to antenna amplifier or etc since I have a Z06.

What about for those of us with C5Z or FRC, where there is no antenna booster?

GM can spec out the radio as "gets great reception with a crappy antenna" and that's what they get. Aftermarkets are made to get good reception in the average metal car.
Try one of these

What's the compromise when tuning the radio to get better reception as GM supposedly does? I don't hear a difference in sound quality... wouldn't it make sense for all radios to be tuned as such?

If you have an antenna that gets GREAT reception, then put it into a radio that amplifies it, there's a good chance you'll get a fair amount of interference or echos on stronger channels. GM is able to match the radio and antenna so they work well together, swapping out gear for aftermarket equipment messes the system balance up. Some radios do good, most not so well.
