    Im guessing you liked my config file/it worked for you! Iv actucally changed it slightly because i realized and read that the sensor i was using to calculate my boost pressure was inaccurate at low boost levels... so now i have one boost calc from the Lo Res sensor and another from the good ole MAP sensor. MAP sensor is accurate down low and it meets the other sensor somewhere around 6psi, I can post the new one if anyone wants to try it

    @ Stromboli...

    The MAP sensor in the lower CP sees the pressure after the turbo but before the throttle body. The turbo starts to build pressure there when it spools up, even when the mani is in vacuum. The one in the intake manifold sees it after the throttle plate. You have the TP in between the two so they should not match until the differential between the upstream and the downstream side (of the TP) equalize. Theoretically there will always be some pressure drop across the TP as it causes some differential even when full open.

    A butterfly valve like the TP has 99% flow once it's 90% open & 70% flow at 50% open. I suspect the pressures equalize in the system for you around 6 psi boost, and why you see the pressures match from that point upward.

    ahh, so i had the right thought wrong reasoning! Thanks IAB

    you wouldnt by any chance know if "If... , Then...." statements work on HP Tuners? I want my MAP values to match my boost Vac gauge in the car but cant do that unless i could use a function to change the value below "0" values!

    I made a custom PID to do it in my config, but it read vacuum in -psi. 2.02 inches/hg = 1 psi.

    I never tried an if/then.
