Hello Ford “Ruckel” friends, after a long time I decided to convert my vacuum box (VTG adjustment) to pressure box (from the Wastegate loader, still had one in the cellar). Nach 1hd I got the pressure box rebuilt and made an extensive test drive (be careful with LDA). At first the loader regulates so with 0.7 BAr. By slow adjustment on the shaft (VTG rods) nevertheless got the load pressure on approx. 1.4 bar. m lower speed <1800 rpm generate approx. 0.2bar more charge pressure. Now to jerk: The jerking is definitiev hardly still there, even after the cold start this morning the jerking is ~90% less. First of all, if you drive for some time and see how this behaves, can not explain it to me. Does anyone possibly have an explanation why the jerking has become less? Greeting
