The reason you don't see a list like that is there are to many variables and assumptions about what a product makes. Some headers make more power than others. There are differnt cams for different applications and how much power you want to make. A lot of the power gains you quoted are the manufactures numbers which are usually not to accurate. Ex. 10)MAF sensor $325 15 hp? I really don't think so If you are refering to the Granetelli(I know my spelling sucks) its common knowledge that its pretty much junk and not worth the money. I think the problem with a list like that is too high of expectations people look at it buy a product based on it and when they don't get the power they were expecting they get :mad My advise for you and new owners is to talk to people on the board do some research and if you can go for a ride in peoples cars who have the mods you are considering.

Re: C5 Power Modification Guide (EB20003)
If I was starting over I would just find a good shop/vendor talk to them about your budget and buy the stuff that really works. I was real resistant to heads and cam at first. Now I don't know why.
1) Intake
2) Exhaust
3) Andy's $3500 Head and cam package or a similar package would beef things up pretty well.
4) Get it tuned.
With just those four things you would be faster then 95% of all cars on the road.
A lot of people spend a lot of money on bolt on stuff that doesn't do much for performance and that stuff adds up fast.
