One of my friends is running a 2007 M8 with and SLP single, SLP air intake, and reeds. He is not running a fuel controller. He says it runs pretty good but the clutting is off a little. What are you guys running on your setups. I believe that he is running stock springs in the primary and secondary. He also has the stock helix. He just changed his weights to the 71 Gram MTX weights that SLP recomended. He wants to gain 150 RPM, he is only running at 7950 RPM currently.
