How much HP should I expect to gain?
I have a 2007 c6 (LS2) that is stock with the exception of AR headers (1 and 7/8 to the collector 3 inch all the way out with x pipe and free flow cats). How much gain in HP should I expect (over stock) from these headers and a proper tune?
Thanks, TJ

35-40 would be my best guess.

agreed with that hp gain, headers and tune is a great first mod!

One of the best starting mods for the LS2/3 engines is a set of headers & a tune

Put the C6 on the dyno last week. I was a bit surprised by the graphs (pre and post tune), but I'm very happy with the way the car runs. Just thought it might have a bit more HP that this.

Your numbers will depend on what dyno machine that you used,,,a Mustang dyno will typically show less hp/tq than a Dynojet machine

Didn't realize that different dynos give different readings depending on the car. Can you elaborate on why this is? Seems like HP is HP independent of vehicle, but I'm no expert.
