I would not put too much stock in just one source especially if it is Dinan. There are much better companies out there. Being a tuner, I am sure you know looking at real world examples is the best way.
For example, this fellow on this board gained 50 wheel HP from the mods he has listed before even the full tune (70 wheel HP with full tune, which makes it around 500 HP crank HP), which are only 4 or so (his baseline is very low compared to stock M3s, but he dyno'ed on a Mustang dyno, which is famous for reading very low and all his dynos were at the same place within a day of each other so all that matters is that it is an apples to apples comparison). You might want to read through the entire thread and might find it informative.

Just look at the Dinan website.
High Flow Intake for $850 = 8hp and 5tq

High Flow Throttle Bodies for $2300 = 7hp and 5tq
http://www.dinancars.com/store/produ...cat=818&page=1
Free Flow Exhaust for $2300 = 6hp and 5tq
http://www.dinancars.com/store/produ...cat=818&page=1
The only thing they offer that will increase your HP and TQ significantly will be a whole new engine for about $23,000 which makes no sense at all.
I have not seen anything else yet so please let me know as I'm very new to the BMW scene. I know this is a very new M3 so it usually takes some time for the aftermarket scene to catch up.
