So I've found the M3post section of this forum completely boring over the last few days and returned to the tunner section of E90post.
There are some truly amazing things going on with tunes and piggybacks for the 335 that are producing large gains for relatively small investments.
I think if BMW over-prices the M3 in the US by even 5 grand, they will see a large number of defectors from the "ultimate" 3 series to the 335. The TT-3 is already a car that can give the M3 a run for its money, and with an easy to accomplish tune will likely walk the M3 in all situations. How embarassing would it be to get stomped on repeatedly or not be able to pass a regular old looking 335 in your brand new, 70,000 M3???
Just so you know, a simple 2K reflash of the 335 ECU that comes with FULL warranty (Dinan) puts down 332 rwhp and 360 rwtq - talk about WALKING on an M3.
