--System pressure is good. (4.7bar, spec is 4.5 to 5.2bar)
--Warm control pressure with vacuum line at atmosphere is good. (2.8 bar, spec is 2.7 to 3.1bar)
--Picking up vac pump today to check Warm control pressure with vacuum applied to control pressure regulator (should be 3.4 to 3.8bar with 520 to 546mbar of vacuum applied)

If the pressure with vac applied is off...that would make sense, except for the symptom going away in corners. I can't think of why the Control pressure regulator would be affected by cornering...
