The 3.5 is a dog and a joke, way to big and heavy of a vehicle for such a puny motor, sorry folks but it is. If you want a 3.5 motor get a 335i, that's where it belongs.

The standard 5.0 runs well but it does have some pretty noticeable turbo lag.

The 5.0 with the performance upgrade has a lot less but still some turbo lag.

The main difference is how much harder it pulls as RPM's grow. It is very noticeable.
In sport shift mode it is a beast.

I encourage anyone to get it as it is a bargain for the noticable bump.

+1 he is absolutely correct... i set a speed limit at 100 for me because this thing hauls ass and every time i looked down at the speedometer i was already doing 110 haha. and all this is while i'm still babying it and not really taking it above 4k rpms.
