Currently I'm running a '91 740 B230F+T, it has a TD04-13c on it with an IPD Turbo cam, Chipped ECU & soon to be chipped EZK. I should get a proper boost gauge (currently using the shoddy stock one), however -- when does boost usually kick in?
If I'm at 3k-4k RPMs, I can see the boost gauge go a quarter of the way over the middle, but anything below that while driving and I'm consistently under the middle mark if not in the middle. I don't know if that's normal (again need to get a boost gauge), or if I've some plumbing or a failure with the actuator or CBV.
Any thoughts?
