I'm wondering if anyone has any experience with any of the following aspects of their signature package:
High flow exhaust (increase mpg? droning on the hwy?)
Bored throttle body (decrease mpg?)
Ram-air intake (increase mpg?)
Front strut tower brace
Basically, I'd like to eventually use this car on the track (for fun, not competition) and feel as though these might be a welcome addition. I would also likely install a LSD. So, for about $4,000 total (including LSD), would I be any further ahead from where I'm already at with my ZSP 6MT? Dinan claims a total output of 270hp and 245 ft/lb (up from 255/220). I realize it doesn't put it anywhere near a chipped 335i, but I love the balance of this car.
Oh, can't forget their aluminum pedals as part of the package...
