Default boost problems...again.

<a href="http://homepages.nyu.edu/~jod204/45degreemorning.xls">Excel file for 5 2nd or 3rd gear pulls- Right click, save as</a>

So. last night at around 55-60 degrees, i was pulling 13.15psi or about 1910mbar PEAK boost.(requested was 1920) Today i hooked it up again...it was about 45-50degrees this morning and i peaked at 12.9 or about 1900mBar (requeseted was 1920mBar)

being that requeseted is pretty much matched to actual boost, i'd rule out any problems with the turbo system....

what confuses me though is why am i only getting 13psi...the only conclusion i can think of is the engine management software realizes it's cooler out, thus reducing boost to get the same amount of power- i could be wrong...but that's my only logical conclusion....unless of course, my APR chip just isn't working right....

can anyone help!?!?

oh- and all these were measured logged using VAG_Com

Default if you get low maf readings, check for intake garbage.
