A4 spraying through shifts...
Do a search. This is one of those highly debated topics.
Bottom Line- I dont think its safe for parts, IMHO, it has to cause premature wear. But I spray from the line to the other end. I wasted the stock trans after 600+ passes, loads of nitrous, and ALWAYS Sprayed through the shifts.

As said above, highly debated issue. Mine didn't fair so well spraying through. Even if you plan to spray through it is a good idea to have a window switch just in case you hit the rev limiter.
I also spray from one end to the other. only for 3 passes i hit the rev limiter on 2-3 shift, i adjusted revlimit and the shift points and i was back ready to go. Luckily it has been 2 years with me spraying this car, and no big problems yet.

I always sprayed through the shifts with no problems. BUT I had rossler rebuld the stock trans with only 11,000 miles. The trans was in great shape but i new it would take a **** when i broke into the 10's. I wont be spraying through the shifts this year with the new motor and a 300 shot it will be more than it can take IMHO.

You're at 345 now and could spray a stock longblock to maybe 450rwhp. Sprayed or not, there's a lot of A4s out there with 450 to 500 hp making many full power runs.
Dont you guys think by deactivating, and activating through shifts that the tranny will get hurt by the multiple shocks of on/off from the spray... versus just keeping the same load throughout the entire run?
I also sprayed from start to finish through my gears on my stock A4 with about 100k until it finally gave out after about 1yr or so of spraying. Like they said its a debatable subject. Every car is diffrent and will handle the spraying diffrent also. But it does cause premature wear & tear. IMO!!

I agree with the highly debated thing. My name is Eric, and I spray through my shifts. Bottom line, whether you spray through or spray-stop-spray, you will lose your tranny eventually (and everything else for that matter). More power = more wear. Think of the boosted vehicles, they can't turn the boost off for a shift, why should you? 
Window switch is just good safety, not made entirely to turn off the nitrous for a shift. Used so you don't spray too low or too high (RPM's).
