So trying to determine a few things on my car, most notably my actuator spring pressure and my boost gauge accuracy. I just put a new actuator on, that is suppose to be 8psi.
I uploaded a log with this post...
At max looks like my map reading is 1.25bar.
How does this translate to psi?
Converting this gives me 18.13psi, which i know is not correct. Using the info from this site....
boostsource and this formula...
Absolute Pressure (psia) = Gauge Pressure (psig) + Ambient Pressure (psia)
That would then mean.... 18.13 - 14.7 = 3.43psi?
Thing is my gauge is reading around 8-8.5psi under full boost/WOT....AEM failsafe...
My old actuator at WOT full boost would read about 6psi.....
This new one is reading at 8-8.5 or so at WOT
So now really confused. Is it possible i setup the preload on the actuator arm wrong? Maybe thats causing the 8.5psi vs the 8psi, or is that small fluctuation acceptable.
But still wouldnt account for the weird datalog on the MAP sensor...
Any input...am i reading something wrong in my logs?

Thanks all!
