Ballpark, what hp + torque gains on a Dynojet should one expect from these mods? Car is a 2010 A6 Grand Sport, LS3, with dual mode exhaust.
Car pulled 352hp/359tq @ the wheels after mods but before tune.
Those 'before' numbers are a tiny bit low for a stock LS3 automatic on a Dynojet (though the Grand Sport's larger wheels/tires/brakes will eat up at least some power) but based on those numbers I would guess somewhere in the 365rwhp/370rwtq range? on that same dyno of course.
Those mods you did only yield so much gain on a dyno, it's out on the track where they will shine more of course.

I also have a 2010 GS, A6 but with the base 430 hp set-up (see side pic) and a "home made" CAI using an OEM filter/assembly, other than that it is completely stock. I weigh 255 lbs. and so far my best 1/4 mile et has been 12.01 @117+ mph running about 5/8 tank of gas. I will be doing the 160* stat and some 19" drag radials soon to help keep the car consistent at the track.
I have not dynoed my car so it would be nice if you could get some 1/4 mile times before and than after the tune for us GS guys along with the dyno results of the tune.
PS: Although this is my first vette, I am a long time fat bracket racer so I know how to get a car down the track, so don't worry about it if your "et" does not get as low.

Numbers are in. 420rwhp (actual, not corrected) or +68. Torque to 421 or +62.
I have a 08 A6 with a Callaway honker, LG 1 3/4 Super Pros, and Corsa Sports tuned by one of the best. The results were 392 rwhp and 397 rwt. I was told that I was more well within the range of one of hundreds of car that were tuned. Results were corrected on a Dynojet Dyno. I have the sheet to prove the results. I would question those results.

A6 here bone stock down to the air filter.dynoed 10-23-10 @8518 mi. on the odometer.sae corrected on a dynojet pulled 374rwhp 364rwtq.so far added an airaid cai,160 tstat.havent gone back to the dyno yet.
: No way you went from 359 to 420 with just a tune......
Agreed. It didn't seem right to me either, that's why I wanted to get feedback on results others have experienced. I have heard that gains of ~ 50hp are possible with a 2010 A6

I wasn't questioning you. I believe what you were told but I do think you need to question your tuner. Your base tune was low even for a A6 and an average jump for a tune is only 10 or so HP. Maybe 15 max. I would think your car should be around 380 HP or so. Say you are at 450 crank right now with the mods with the 18% drivetrain loss you would be around 369 RWHP. I think the LS3 is rated a little low on the HP too. Hope this makes more sense. I am not a tuner but usually the good tuners say ~18% loss for A6's.

Ok, notice he said ACTUAL numbers, meaning completely uncorrected. Given his location and the fact it was probably pretty cold outside (40s? i'm not from there so I don't know). 40 degree temps + low humidity the car could make ~420rwhp, but then corrected he'll be back down in the 390's, which is where the car should be.
However, why the **** would the tuner give you corrected stock pull, but then uncorrected after the tune pull? Sound like shady business.

being a 2010 means nothing whatsoever, so stop listening to the people that are telling you that.
I was simply laughing at the thought of gaining ~70rwhp from a tune on a stock car and you simply stating "numbers are in" like it's a possibility.
If you're not going to be helpful, why bother at all?
This is not the forum for teenagers with nothing better to do. This is the Corvette Forum where like-minded enthusiasts come to share knowledge/gain experience. If you need to do otherwise, stick to twitter.
As for the "numbers are in", I am simply stating what the results that were given to me were. Nothing more, nothing less. Reading anything else into it makes me think you must be a regular on the Subaru Impreza forum. Do us a favor, go back. Leave CF to the adults.

I think one issue here is you 1st dynoed after installing mods. The intake possibly reduced your HP/TQ and the tuned got it back, and then some. Even still there is something funny going on. 420/421 is better than my LS3 MN6 did WITH LG long tubes and X-pipe. My numbers are 419/414 but that is SAE corrected (the numbers are higher in Standard mode)
