I do it from the top. Top righty shorten, lefty lengthen. Shorter acts quicker, and longer is slower.
Bottom is opposite.
I am not trying to confuse you.
The best way to express the concept is from the top you're adjusting to the turbo, right for more boost, left for less boost.
From the bottom you're adjusting to the actuator, left for more boost, and right for less boost.
I want to see 100 to 138 over on the log spike and 500 throws limp mode. The ECU will inject more fuel if MAF readings say that it needs to. So more over lowers fuel mileage without the tune to tell it otherwise.
The ecu will adapt to the settings so long as it's within range of its adaptation capability.
