Low Boost issue - what can it be?
<center><img src="http://www.koshok.net/tt/boost/run.jpg"></center><p>
Solution: turns out the N75 was installed incorrectly.
Hi All,
I have a 2000 225 Coupe Quattro and it only is able to manage 10-11 PSI. Something is not right.
I tried unplugging the MAF.
I tried a spare MAF on hand.
I tried a spare N75.
None helped.
Any ideas?
If anyone wants the CSV file, it is at:<ul><li><a href="http://www.koshok.net/tt/boost/run.csv">http://www.koshok.net/tt/boost/run.csv</a</li></ul>

assuming it is a 225 as there were no made as a model 2000, they were 2001's>>>
your MAF readings are low, but not terribly so....what does block 32 say?
If it is a 180...then the MAF readings are fine

APX motor. This is an EU car. They had 225 in 2000
5.6% and -0.8% for block 32.
Seems there is a Vac leak.
It got a TTDA, Evoheatshield, DV relo and an O.CT flash.
New O2 sensor,
New plugs,
New AIT
New MAF
Cleaned injectors
New fuel filter
Any ideas?
