There are so many variables...I cant stress enough not to get caught up in the numers game. Most tuners or shops can help you get where you want faster if you tell them how you want your car to perform, rather than ask for mods to try and duplicate an HP number.
I have a few friends, all with different make and high HP cars, and every one likes to talk about HP, Torque, etc. I have one "friend" (friend being extremely relative
) who claims 700 HP, yet my lowly C6 with just an intake, tune and 4.10s blow him out of the water in every run from a roll or from a stop to any speed....and I only have 365 RWHP.
Mods and tuning are about making YOUR car PERFORM the way YOU want it to. Whether you want to run 11 in the 1/4 or carve through Lime Rock, if in the end your mods get you to where you want to be, dont worry about the HP numbers themselves.
A number will never give you a thrill....but snapping your head back with awesome excelleration and g-force surely will.

Our Canadian visitor showed up today, baseline dyno pull with his 2006 M6 with Corsa Sport exhaust, made 338rwhp and 330rwtq. After tuning and some go fast parts, it made 353rwhp and 362rwtq. Net gains were 23rwhp and 24rwtq. Numbers are non number corrected since I had to give those reports to the customer who's on his way back up to our neighbor to the north.

I understand this. My point is overall gains from bone stock to mods and tune. All the confusion would have been elimiated with a dyno run as bone stock, which I know you got it after mods. A 16hp tune is respectable. When you see some C6's dyno bone stock (no tune) in 340-360 range, it makes you wonder just how bad this car may have been stock.
I'm sure that's what you meant though, right?

Keep in mind, too, that we DO NOT lock up the converter when we do these pulls. There are quite a few tuners who lock up the converters, to make that extra power on the dyno. There are also tuners who have broken many a car locking up the converter. We don't play dyno games, and we don't cheat, just to make a number.

I didnt realize this was a mustang dyno...in that case Mustangs really are the best dyno for tuning and the output goes beyond just a basic whp measure by adds in other factors as well.
Mustangs really are the best dyno for tuning and the output goes beyond just a basic whp measure by adds in other factors as well.Why would it be the shop's responsibilty to get their dyno in line with other local dyno's? In our area, there are not many Mustang Dyno's like ours. I'm not going to inflate numbers (which is very easy to do with a Mustang Dyno) just to have to compete with the other local shops. They can tune cars and get as high of a horse power they want, I'm far more concerned with getting the AFR and Timing correct, as well as the 1/4 mile times. I've seen this go both ways, 368 SAE rwhp (Mustang MD-1100SE 4L60E locked converter 3.54:1 gear) 02 F-body runs 11.6@116mph. 535 SAE rwhp (same dyno, 3.90:1 gear, unlocked converter) ProCharged 05 C6 ran a 12.5@135mph. Dyno's are a tool for tuning, not a benchmark for performance.
All that being said, stock A6 C6's are dyno'ing 325-330rwhp on our Mustang dyno in 4th gear. As for M6 C6's, I have yet to get a base line, everyone that's been on the dyno have had mods, except one that could not be baselined due to time and dyno availbility, but it produced 375rwhp after just bolt ons and tune. I have a stock C6 coming in from out of town tomorrow, and I'm going to be sure to baseline it regaurdless, and have final numbers by Saturday, I'll keep everybody informed.
Net HP gains are what's important here. Cars are only going to make as much power as the air an engine can move through it. Air is the limiting factor, unless you starting moving more air in, you can only add or take away fuel, or add and take away spark.

I had my '06 C6 A6 tuned today. I know there are variances with dynos and such so I can't really say much beyond posting my numbers. Tuner used HP Tuners software tested on a DynoJet.
I am stock except for a Vararam CAI w/TB which doesn't really mean squat on the dyno. Car has a little over 10k miles.
Baseline: 330.81 rwhp 339.83 rwtq
After Tune: 348.06 rwhp 353.82 rwtq
Tune sheet says, "CF: SAE Smoothing: 5". Temp was 73 deg w/ 32% humidity. Posted runs were 40 minutes apart.
We made 6 pulls to readline in 4th @ 175 mph. You could hear the sound change and get chrisper as it was dailed in. He was able to take out alot of the TM and removed the delay in applying power below 5k rpm. Car feels much better but the real test will be in two weeks when I autox it again. Last time out I really fought the throttle lag.

As stated #s are #s........lots of variables.
Our 00' A4 Coupe with LTs/CA/CB & a tune dynos 312hp/322 tq unlocked at 3 different Dynojets in our area..........
but has turned at best of 12.47@112 mph at the strip!
A dyno is another tool for tweaking tuning, not the ultimate prover of power........a 1/4 mile run's MPH is

Has anyone just figured the car in question is a dog?
I have tuned many cars over the past few years and have seen exact cars back to back on the dyno produce numbers 15 rwhp apart.
Same day same dyno 2006 Z06s first one 453 rwhp and the 2nd one 464 both black just incase you want to say one color is faster LOL.
The dyno in question is not a factor, I have known Tracy and his family for some years and Dino's rep. is gold.
The car is a dog, maybe from the factory or the way it was broke in.
