You'll probably see the most noticeable improvement from the VANOS adjustment speed alterations. It really alters the responsiveness of the midrange. Also, the SMG changes bring the transmission to what I feel we should have gotten from the factory for around town driving.
Hi Jim, a quick question regarding the VANOS adjustment speed alterations and responsiveness: one of my gripes with the S85 over the S65 is the lack of linearity compared to its smaller cousin. Is this something that your VANOS tuning is able to address or is it an issue innate to the S85's volumetric efficiency?
