I drove mine for about 100 miles total before the tune, but I am running 42# injectors and E85... I can promise you this, it will not idle worth a crap untill you get it tuned.
I will say this though, if you have access to a trailer just tow it because it is a big gamble on how it will react, I have talked to four guys with the same cam and we all had different results. You didnt state if it was an A4 or M6 car, if it is an A4 you better get a big stall in it!!!!

 

You drove it 100 miles on the stock tune with the 42# inj and E85?

 

that's how i read it too, but that's impossible.
