boost psi doesn't seem high anymore???
when I had a dahlback chip done back in Oct, my boost psi was hitting 19 psi then dropping down to a hold at 16 psi. Now for the past month I noticed that it won't peak at 19 psi anymore, it will just peak and hold at 16 psi.
Why the sudden drop?

could be lots of things >>
Maf's, DV valves, sensors, etc. Not the weather.
Example of O2.....just got my big bore conversion back....hit 30psi. Within a week she wouldn't exceed 26 and nailing 5th on highway got 19 and dropped from there. One new O2 sensor later and it's hitting 30-33psi continually.
Any codes?

I beg to differ......>
Weather does make a big difference, especially Temperature changes. Barometric pressure is also read by the ECU and used as a compensating factor. Mr DB may have circumvented all that stuff on your car, but for the rest of us it is a real factor..

i knew you beg to differ>>>
I see no change when it gets cold. going from Oct to Dec should not make the boost drop like that....
Hans isn't any different. My APR100 oct chip worked the same in cool weather as in cold. Only very hot did she dial back.
