Just off the dyno
Just got home from spending most of this afternoon at the dyno with my 07 w/6spd paddle, Corsa sport exhaust and SLP Blackwing. After meny pulls the results are 388.5 HP and 351ft/lbs of torque.Up 16HP from the first pull. Do these numbers sound right.?

While I can't answer your question, I'll take advantage of your post and ask you a question (hope you don't mind). I also have a 07 a6 with a blackwing and a SLP exhaust. No tune or further mods till warrenty is out in Dec. Question # 1, How does your car shift on the 1-2 shift? Mine is sluggish, but all other shifts are firm and quick. #2 any drag strip #'s.

No, it doesn't sound right. It sounds about 40-45 rwhp high. Most A6 LS2s dyno around 370rwhp with your mods PLUS longtube headers. ~390 would even be on the high side if you had an LS3 with those mods, lol.
My car dynod 387 with K&N intake, Ported FAST, Catless Longtubes and Borla Stingers.
Were the numbers SAE corrected? What kind of dyno?
FWIW, picking up 16rwhp is what's important and that's a very solid gain. The dyno just seems to be dynoing on the very high side, but the gains on the same dyno are what's valid. Money well spent on that tune, I'd say.

Hey jflack; I am surprised you did not get a check eng. light with your mods. but i did remove the honeycomb from the MAF that caused all the problems i was told. As with the check eng. light on the car not only shifted up ****** i got a big clunk when it down shifted when comming to a stop. As said i just got her back tonight and have not spent much *** time in the seat but she seems to be nice. I will take her for a good ride thie weekend and let you know.

Almost dynoing 390rwhp is definitely WELL above that range.
390rwhp is at the high end of what a full bolton LS2 A6 will dyno.

You'll need far more than that... We'll need to see documented proof of the calibration as well. If you could get a copy of that, scan it and post its image it would be much appreciated.

b murph-Help-I'll ask again Does you 1-2 shift seem more sluggish than all the rest??? Not trying to be a smarta$$ but you have the exact same car as mine and I got no-one else to ask. I had this issue before any mods. Dealer says the factory will not do anything about it, its not bad enough. I have no CEL problems so far.Thanks!

The LAS dyno is probably one of the most accurate out there. However it comes down to the operator. That dyno has to be configured for your car, it needs to know the weight and engine size plus a couple of other things like axle ratio and gear ratio the car is running in. If these are not inputted correctly the power numbers will be off.
With that being said most LS2's with 6spd manuals out the box are in the high 340's so I would say something was not configured on the dyno right. Once all the right numbers are inputted though, I would trust what that dyno spits out before anyone else's dyno.

Hey jflack; As said before, I took the honeycomb out of the MAS and got a check eng. light that was both banks running lean.Only 15K on her. Up shifts seemed OK but what i got was a big CLUNK when comming to a stop from 2nd to 1st. In paddle mode there was no problem. After the tune ever thing seems fine except a little idle studder once in a while. Maybe it's time for you to get a tune. Just don't post your #s here.
