Can you data log or graph desired boost against actual boost & N75 duty whilst flooring it in 3rd gear to see how the boost control is reacting, also useful to see what is actually occurring on the vac actuator with a vac gauge.
Do the atmospheric & boost pressure sensors tally with each other with the ignition on engine off etc.......
Does the manifold runner vac actuator hold vacuum on a mityvac?
