More power please
I recently purchased my Z06 with the Z07 package. I am very pleased overall but was expecting more from the car in regards to acceleration. I had a built '99 C5 making approximately 663 hp at the rear wheels (centrifugal blower with meth, etc) .
I did not think that I was going to feel the difference but the Z feels lame compared to my C5.
Looking for others to get some ideas.

The best mods you can do without having your warranty affected in my opinion is a Halltech Intake and a Corsa X-pipe. The intake really wakes the car up since the stock intake is pretty restrictive.

Headers
I have spoken to my builder (Slowhawk Performance) and he recommends long tube headers, Halltech intake and a tune. Not sure if the headers included an X-pipe but I assume so. I am not sure if all this would be a issue with the warranty.

Well if anything happens to your motor and GM sees it was tuned, they might blame the motor issue on your tune and deny fixing the car. That's the biggest thing to think about if you're considering LTs and a tune.

The newer generation cars are sooooo much more refined and smooth that the great leap in performance isn't felt quite like the driver thinks it should be. This is especially true with the C7 because it is even more refined than the C6.
In your case your C5 was very close in horsepower, and I guess performance, to a ZR1 or C7 Z06, but I'm sure it had a much more "raw" feel to it.
In the C7, the seat-of-the-pants feel just doesn't make it seem like the car can possibly be accelerating as hard as your C5, but it is - it's just so much smoother your SOTP feel is fooling you.
Do some acceleration comparisons and you'll probably find the cars are very similar in performance even though the SOTP sensation isn't telling you that.
Let us know what your comparisons based on timing tells you.

Yours was a fairly common complaint when C5 owners started getting into a C6.

I was thinking the same thing
, but you've probably considered this possibility. After break-in, take it to the track.
Did your modded C5 have a significantly different throttle control system with a sharpened throttle response through mods?
Take your C7 and find a long tunnel, roll the windows down and hammer the throttle with the exhaust open. If your Sport Cup 2's are warm and maintain traction, your senses might give you a new opinion of the acceleration.
Just a consideration, and no mod worries to affect warranty.
And, of course, stay within speed limits and keep the car straight (nannies on).

I've currently got over 600 rwhp and this was my fear too - being disappointed with the feel of torque that is evenly distributed, especially after spending $100K. I don't have the car yet but I'm preparing myself mentally that I will not feel that kick in the pants, especially around 4,000 rpm, like I do now. So between lowering my expectations, combined with future plans to modify (Halltech, headers, and tune), hopefully I won't be too disappointed and I'll know that I'm going to make the car faster with bolt-ons and a tune. Strategy!

Well...you're mainly paying for the Callaway brand and warranty. You should retain at least half of the $17K when you go to sell. Regardless, you'll have piece of mind if that is an issue. If warranty is not an issue, then I would definitely go a different route.

If you go H/C/I for about $5K, and your engine takes a dump, no warranty, you're looking @ $25k~ for a crate.... So, while rolling the dice you could potentially end up with a $30k head ache? Plus, don't forget loss in value when going to sell compared to increased value on a Callaway.

No great reasons to do headers on these cars. You might pick up 15 HP for $2k. Just put an intake on it, and if you end up wanting more, then go for a procharger or a different blower.

I think they are getting more than 15 with a tune, especially when paired with CAI. I've seen guys with CAI, exhaust and a tune getting close to 100.

That would make the C5 have way more power - so I don't know why he had any expectation that his C7 Z06 should keep up with it.
