LQ4 maybe not... Should be pretty close still if you let the fuel trims max out a bit first... E85 has a large tolerance range so your afrs can be off a bit at wot and it wont cost you performance or safety.

If "getting a tune" is not that easy for you down there, I wouldnt worry about it until after you find problems with the stock tune/whatever tune you have now assuming you have it tuned for 33lb injectors. The key to the "e85 on a stock tune" is being tuned for 33# injectors and swapping in the 42s with the E85 at the same time.
