Guys, this is a GREAT deal at Carb Conn and Powerchip seems solid as well. What a fantastic way to prove or disprove claims.
Bring USB sticks, you can take your dyno files home and download free DynoJet software from DJ web site.
Last stock M3 that dynoed there put 333 WHP against my slightly (headers) modified Cayman S at 289.
Please post results here as I am CURIOUS.
I am lurking here as I am considering M3 as my next car. Wife wants me to drive something with room for kids.
I do not want to jack this thread, but can someone point me to threads on occasionally tracking the M3 and dealer warranty. I am likely to install springs and BBK on the car as well.
