Thanks for your quick reply SK,
I'm still a little confused about this..
If I set all the Output pts to 0. Regardless of throttle position, should I get the same boost (give/take a little) at Input pt 19 in 2nd, 3rd and 4th gears? (On a flat road)
If the answer is yes, then my car doesn't behave this way.. I get much higher boost at Input pt 19 in 4th gear compared to 3rd gear. About 15psi in 4th compared to 11psi in 3rd.
Does Input pt 19 mean different load in different gears?
