What kind of dyno do you use? I'm assuming it's an awd dyno since you do subaru. I am shopping around for a tuner for my 04 forester xt that I'm building an engine for right now, and I'm sure I'll do some upgrades to my e36 sometime soon and will need that dyno'd or tuned as well. Very interested. Matter of fact I'll be in Kohler in a couple weeks.
