not yet. The 8v was covered in the June issue, the VR6 in the July issue and the 20v in the August issue. Therefore I'm thinking the September issue will cover the 16v. Just a hunch. There's loads of info on the 4motion Halex drivetrain and G60 charger in those 3 issues too. Well worth a read. The June issue talks about the 16v engine and why it's so good, but doesn't talk about tuning it in depth.
