I didn't get any of the details as far as dyon results, I did'nt want to push him on the questions, I'm sure he is getting bombarded with the same questions everyday. I was told the they will have a non DPF("off-road") version of the S67, don't take my words for it though, it didn't come straight from Stefano, just from a guy that was out watching the dyno tests. I can't imagine MADS not releasing an "off-road" use tune. I'm under the impression from what I heard that it will just require you to sign an off-road use only waiver. I guess we'll find out, I don't know how long they generally run a beta test.
