Haltech + LG + Tuned 2006
Just got some upgrades to my 2006 Z51 MN6. All runs had a Haltech CAI installed.
Lowest line is base. Top is with addition of headers, 10mm spark plug wires, low temp thermostat and tune by MTI Racing in Atlanta. Middle line is the hardware above with reloaded factory tune to see how much the MTI tune got us.
Torque is looking good!

What are the SAE numbers? Easier for me to compare my combo. It seems the LG's combined with a 93 octane tune make for good numbers. Certainly better than my Kooks/91 octane tune

MTI has JUST started tuning 2006s. They notified me about 2 weeks ago that the software was working.
And I don't know the SAE numbers, but will ask the shop.

Anyway, for what it's worth I think this is what I was told.

I am pretty happy with an overall of 31.1/35.6 over that with just an intake and 384.7/389.5 is about as good as I've heard of for bolt ons.

As to what sounds right and what we read here on the forum, header numbers seem to be one of those fine mysteries of the universe. Compare this graph from another thread that's now alive in C6 technical: graph link thread link. Who knows what's tune and what's headers?
Bottom line: get an honest assessment from a tuner/seller that you trust, and hopefully that way there's no surprises after the work is done and the money is spent.

They told me the SAE factor was 3, which I guess is the "smoothing factor" - whatever that is.

SAE Corrected Graph
Well, the guy who actually tuned my car got back to me and agreed that the graph previously posted was not SAE corrected. He sent me the attached graph - unfortunately he dropped the run with headers only, but at least this is now accurate.
Still pretty happy with the final numbers and the increases were great.

This is my first 'vette, so I don't know what words are normally used to describe this, but...
Originally the car felt like it would "surge" forward when you punched it pretty good and it felt very nice. There was this feeling of a huge amount of controlled power building up, rapidly but not instantly, as revs increased.
Now it feels like the car will just jump out of it's skin from 2500 rpm+ all the way to redline. Floor it anywhere in that range and tires will spin in first and second even with traction control on. You definatly cannot just punch it going around corners or the active handling gets really stressed! In a straight line third gear feels like you've been hit from behind as the speed goes from 50-90 about as fast as you can think about it.
Wow! - Definatly have to get used to this before I can even begin to wrap my mind around what other people's reported 480+ HP must feel like.
