I decided not to go sledding today and it cost me more money than if I had. I pulled down the 09 m8 and I am taking the cylinders to SLP on monday to finish the performance package. I allready have the slp pipe and intake so I am going to have them port it, do head mod, and install the power commander III. For those that have ported there's what weights are you running in the primary. Right now I run 70's with just the pipe and see 8000rpm at 8500-9000ft. With the porting peak power is at 8200 so I might just leave it alone and see what I get.
