Hey Steve...Boost Machine tuning question...>>>

The Boost Machine is installed, and it is set at 4-1/2 turns on the boost valve and 1 turn on the onset valve. Boost peaks at about 22 and settles in at 19-20 (on an APR chipped 225Q). The car is definitely much better than before the install.

Your instructions say not to push it much above 22...do you mean peak boost or what it settles in at?

Thanks!

And for those of you thinking about getting a Boost Machine, I highly recommend it. It is a super easy install. If I can do it, anyone can!

Interesting... I'm set at 5-1/2 turns on the regulator to peak at 22psi. Outside temp difference?

Partially...>>

Plus you're setting to a desired pressure point. Regulators are not precision instruments in that # of turns will never be the same from valve to valve. They are adjusted to the desired pressures within thier range....There is always some variability...
