Ha, I guess I deserve that, for not being thorough enough in my description. Yes, the boost varies according to throttle position. It ramps up extremely fast, and is pegged until with 200 rpms of redline. Here's a chart of my '08 135 (n54) with Dinan Stg 2. i'm just cruising along the highway in 2nd gear (the cluster of low boost dots, and then accelerate with WOT until hitting redline
the drop-off visible in the graph is quite noticeable while driving.
If i'm hijacking this thread, let me know, I will start another Torque affinity thread. Like finding an Oil Temp PID, tips, tricks and such.
