From: Greater Detroit Metro MI, when I'm not travelling.
The setup was:
2006 C6 Z51
Kooks 1 3/4" Headers with a catted 3 x 2.5" X-Pipe
GHL Exhaust
Vararam Intake
160F Thermostat:
Between the haders, exhaust and intake the car had about $3500 in mods, and was making maybe 14hp over stock. The tune brought that up to 40whp over stock. I feel that modding your car is not worth it (in terms of hp per dollar spent) UNLESS you tune.
My advice is to figure out how much power you want, get the mods that will get you there, and tune it all at once, otherwise you will keep on comming back and spending more money. The dyno above kept me very happy and entertained for about 12000 miles or so, then I wanted more. I ended up supercharging; the blower makes me wish I had gone that route before; it is everything I ever hoped for and then some. Its been 4500 miles and I still can't wipe the grin off my face every time I drive it

I had the opposite affect that Powerlabs had. I had an inlet and headers and picked up over 30 in rwhp and over 40 in rwtq. I'm guessing there was something badly wrong with Powerlabs car if it only picked up 14 hp with those mods.
I only picked up 5 rwhp in the tune, but the car was more consistent.

I just installed a vararam, car is mostly otherwise stock/untuned, except for some BB Bullets coming out the back.
The dyno numbers are hard to pin down, but their website claims 15 rwhp on a dyno, and increasing gains from there as you blast down the highway and it sucks in even more air.
Cutting the shroud with a Dremmel wasn't all that fun, but bang-for-the-buck, the CAI was a great mod, even un-tuned. I'm pretty sure that the CPU felt the "new air" and adjusted the AFR to optimize the new breather...
Still undecided about whether or not I'm gonna go with headers/cam, or SC down rhe road - it'll definitely get a tune at that point.. .
For right now, just adding the CAI (no tune) - makes a BIG SOTP difference.... the Bullets made a difference too, but just in noise, no + or - diffs in HP with the exhaust, but the CAI (Vararam, LS2 in my case), has really pepped the aleady quick 6.0L up noticeably.

Anyone get a tune on a stock MN/MZ6 and pick up any gains? What I've read leads me to believe that a totally stock C6 is only worth tuning if it's an A4/A6 - shift points and TM, to be exact.
I'm still wondering about this nearly dead thread to see if anyone had a stock manual car tuned (Predator/Professional - whatever) and has dyno numbers to prove it helped.
