I am running a VHP 056, 216/224 0.551/0.551 115 LSA and my mileage is unchanged, if not better than stock now that I have on the heads and bumped my compression to 11:1. 
Your biggest mileage loss will be due to your trigger happy right foot

Lets all be honest with each other.....
DID anyone buy a C5 for gas milage.........
If you did than you made a bad choice. There are a lot of other cars out there that get better milage...
Just joking, it is go to know how mods effect gas milage.

Mine didn't change a lot on the highway. I just did Long Island to AC and back and it averaged 22mph in an A4 w/3.42s. I didn't buy my Vette for the gas mileage, but the fact that it is decent is a big plus.

3.42 in an A4 really hurts gas milage. I went from 26-28 to 22-24 on mpg.

My tuned custom comp cam (228/232) is still getting me 30+ on the highway and 20+ in town (averaging 20-22 with 50/50 combined driving and warm ups on cold mornings). The trick is staying out of the pedal!
I'd say that most mild to mid cams (anything less than a G5X3 or similar) should get you the same or better econonmy than stock assuming they're properly tuned. When you go real radical and super high lift, you end up getting a very inefficient idle/part throttle which hurts fuel economy significantly.

What to do? Power or gasmileage, power or gasmileage, power or . . . POWER!

Haha... must have been some major traffic, though in NY I'd believe it! J/K - I knew you meant mpg.
