NOTE: adjusting the base boost on DI/APC cars requires MAX BOOST RECALIBRATION. Set base boost as outlined above by unplugging
the solenoid and driving with a gauge attached. Boost is adjusted by the wastegate rod. Then the system must be readapted for
max boost. With the APC solenoid reconnected, jump pins 1 and 2 of the throttle switch together and drive as if testing base
boost. This may take several attempts before the ECU resets the max boost it allows. The car will die at idle with the pins jumped,
so you have to work the gas to keep it running. Pick your recalibrating route so you can undo the jumper after it takes. You will
see it go well into the red and then come back. When it readapts, the distance into the red will not exceed the dotted yellow lines
by very much at all. Most of the time, this works fine, but I caution that sometimes, ISAT is required to clear the ECU and get it to
readapt. This is rare, but does occur.
