How this look?
I took a pic of the peak-n-hold on my PFC...I also have a pic with the engine off...Can ya'll tell me if some of this looks ok or not. The knock level looks a little high to me...I still need to get it tuned...Also the boost sensor, when the engine is off, reads about -22mm/Hg; is this normal or should it be 0?
Thanks

The vacuum display is normal, the Commander does not display the correct pressure reading due to an internal conversion error...
The peak knock value is worthless, as shifting and tranny noise can drive it up....the only time a knock reading is of any value is during constant WOT. 66 would typically not be a worrisome number in any case.

cool thanks...and while we are on the subject of things not right...My vacuum is around 520mmHG at about 1100rpm...does this sound ok..also the car surges--maybe a vacuum leak--except when AC is on idles just fine...when the compressor shuts off--idle surge....where are typical vacuum leak spots located if this might be a culprit? Also when the engine is cold the engine revs up to 2.5k and then drops to 1.8k...it wont settle until the engine is warm about 70°C...it then begins to surge unless the AC is on....CAn I adjust the start up idle when cold...this is driving me nuts!
