Hey, Tim:

At 4.5 turns, all is well. Gas mileage has not degraded as much as I initially thought, and can be attributed as much to my more frenetic driving style immediately after the adjustment by way of testing the adjustment, as to anything else. No deleterious effects whatsoever. Unlike Terrence experienced with his attempted 6.5 turns, I've received no faults codes as a result, and no overboost conditions. Rubber may be left through no heroic efforts, if not careful, as a measure of immediate thrust. Driveability is improved. Its a safe (if not overdone), positive adjustment, for those who enjoy such things.

I've found that there seems to be some variance in initial factory settings, which I've not been able to determine a pattern in. Some folks, like me, have no initial 'pressure' on the actuator arm when attached to the lever....Others say that there is a definite tug on the arm, as it needs to be 'stretched' to make the hookup.

My point is that whereas 4.5 turns work for me, for others who perhaps had an initial higher setting than mine, maybe less would work....My results and ultimate adjustment resulted from about 5 or 6 different trials with different amounds of 'screwing'. I used the ability to spin the wheels on a flat dry start as a measure of thrust immediacy. 3 turns didnt do it. 6 turns did, but made it too difficult to control in the wet, and mileage suffered more than I wanted. And, I tried other settings, finally settling on this...

But for your piece of mind, most folks seem to find it a safe procedure when done prudently. And of course, if you have the equipment, the best way is to use a gauge, although not absolutely necessary..just be careful. --
