good VNT upgrade for a K14
On the VNT- are you using an N75 valve for the vacuum control? I presume what your referring to as the stop is just the free length on the actuator arm? That's how the TDI is setup and if memory serves, the extended position set the vanes as closed as they should go without constricting the exhaust enough to effect idle. The actuator then opens the vanes as requested boost levels are approached to prevent an over-boost and to limit boost when loads are not present.
I presume baldur will have to setup another PID strategy for VNT control? Or are you guys trying to control Boost as it relates to exhaust back pressure as well?
That's surprising on the manifold. I'm following this: https://forum.ih8mud.com/threads/white-l...338/page-2. Lots of good info and it seems he got the probe in the manifold.
