Who said 20 hp/tq gain for the Z4 M coupe (it still has to be determined on the dyno as RPI stated "release is only to be determined when we can confirm actual hp gains on the dyno" ...as far as the E60/E63 M5's they gain 15-20 hp on the scoops and that was proven on paper (dyno)...check the link posted on the M5board...so if i see a gain of 5-10 hp/tq i will be happy (and for a small price)...

Smells like a troll to me. Is this your first spin around the block or what?
