I will point to post #30 again

[QUOTE=RJ999;825335]reading 24 when pushing 28 psi is a perfect reason.[/QUOTE]

22, 24, 28 etc are just arbitrary numbers. That's no proof in any way that the tuners software is not configured correctly.

Hate to break it to all of you.......

If you are running a mechanical boost gauge or cheap digital gauge or even any NON self-calibrating software to read CAN data - then you aren't seeing the 'actual' boost pressure because none of them take into account the current (live) atmospheric pressure.

All map based ECU's do - so what the tuner see's is the actual boost pressure with atmospheric variance taken into account - what you see isn't.

Vi-pec lists it as BAP (Barometric Absolute Pressure)

Just a thought are you using the same turbo as the last engine??


You may have a questionable actuator your old motor leaned out .. Yea cat was removed so would bump up boost a lil but if gate is stuff then even more then usual .....now it's over boosting it. Could be something to look at

using the Perth-WRX mobile app

Yeah same turbo mate. Is there a way to diagnose if the actuator is working properly?

Pressurise the actuator with a mityvac and see what pressure it begins to open the w/gate.
