APR CHIP Boost test with VAG-COM
Has anyone done a boost comparison between the 91 octane APR program and the stock program? Does the VAG-COM give accurate readings for this parameter?
The APR chip is supposed to be in a 1 bar configuration. This would mean the Boost as read by the VAG-COM should be ~2000 mbar. Logs of my boost show readings in the 1700 mbar range which makes me think that I have a boost leak...
Thanks in advance!

Re: what rpm range is it 1700 mbars?chip does fall off at high rpms but should be 2000mbars at 3500
Peaks out around 3000 RPM between 1700 and 1800 mbar then is pretty level (low 1700s) up to ~6000 RPM.

to me your stock boost is pretty high, i think it should only be 600 to 700 mbars over the idle 840
mbar reading. 1000 mbars(1 bar) over 840 is 1840 mbars so you chipped readings appear to be close to right. if requested and actual boost stay within 100 mbars of each other from 3000 rpms up i would guess there is nothing wrong. the stock mbar reading is the one i don't get.
