If you only gain a tenth in the quarter, you won't get multiple tenths before then.

Two mods on my list that I am considering for my 2007 A6 LS2:
1) Change from 2.56 to 3.15 gears
2) Add LPE Heads to complement a GT11 Cam (+20~25 HP)
Wondering if anyone has any regrets on the Gear swap?
My intended use is for street driving mostly around town and the occasional road trip. Car sees road tracks a few times a year. Currently putting down 400 RWHP.

Here is my two cents;
2005 A6- upgrades; Hall-tech Cold Air, 92mm FAST Intake, Mega Death .629" Cam, Cooks Headers, after market exhaust and Tuned to 440 RWHP. Very most recent upgrade was a .373 gear change, raised my RPM's 400 at 70 MPH. Improved my 60' from 2 to best 1.8 on stock wheels, tires and suspension. Best E/T 11.82 @ 120 MPH and cannot wait on the M/T Drag Radials late next week. Good luck

4L60E was only in '05 and by higher HP, I meant 500+. You can always bump the rev limiter a taste if you're hitting it near the 130 MPH area in 3rd, assuming the cam and springs will handle it.
You might consider LS3 heads as a low priced alternative. IIRC, they're around $600 new, including valves. Check with your local dealer.

Update: Thanks for the input on this thread. I went with an RPM Transmissions 3.15 Diff also had a few other HP adders since last year. Very happy with gear selection.
I gave the car a wife test today. I was on a empty stretch of roadway with my lady and I asked if it was okay to do a 40 to 70 WOT pull. Wife agreed, disengaged the wife brake and took off...
I asked her if the car felt different on acceleration (full well knowing the car is a beast). She said she was not only pushed back in the seat, but was also lifted off the bottom on the seat. LOL!!!
