C6 Vette with bolt-on's results
 

So far my 05 z51 has:
Vararam intake & tb spacer
American Racing 1 7/8" LT's w/2.5" x pipe w/cats
Shaner Ported TB
Formato Ported Intake
Corvette Genuine Accesories exhaust(borla touring equivilent)

The car put down 336/345 stock. After the first round of mods the car put down 345.80whp and 346.93wtq on the stock tune. I did a total of 3-4 pulls. I still have some more tuning to do, but this tune is with 19* of timing at peak tq and 22* at redline. The fuel is still pretty rich at 12.1-12.6 across the rpm band. Leaning out the car and a degree or two more of spark may get her close to 395 or so. I'll be switching out my X-pipe to a3" version soon as AR headers clears their back log of orders. This graph from first pull to 3rd pull can be seen below:

This week the blower cam gets installed. It's a 228*-234*-.630"/.600" 114LSA. Should make some good power. I'll keep you guys updated.

Wow, 336 stock to 388 with bolt-ons.

How was the quality and fitment of the AR headers?

Very nice gains man across the rpm band w/ Bolt-ons & way to go blown guy :devil:

Quality and fitment of the headers was excellent. The collectors are really something else. All the welds are ground down on the inside of the piping.
