ok so after this big snowfall ive had to plow my own way thru a few local roads that hadnt been plowed yet, then when i drove back to my college on the road i notice the supercharger acting funny, it seemed to be fluctuating alot and its its average levels were higher than normal, i set my cruise at 65 (dont worry the hgihways were plowed and dry) and normally down will read -10, level ground will be -8 and uphill will get around 0, tonight downhill was around -8 cruising was -5 and uphill was +1 to +2, i dont really know what to make of it, i doubt i was carrying enough ice to weigh me down that much, i've driven in colder weather and not noticed anything like this, ive driven in windy condition and not had anything like this, but could snow in the intake have caused this in some way??

the cold air likes to make more boost

he already saud it drove thru colder windier weather before with no change. Did you check anything under the hood to see if anything was out of place ?

well, the stupid state cant plow the roads for crap, i was driving along and then out of nowhere suddenly the road wasnt plowed at all, 45 mph on plowed road rigt into a foot of snow, the force of that filled my whole bumper with snow o the radiator was getting partisally blocked being that i couldnt get it all out

You are using more power driving through snow than on clean roads.

Simply put..you are requesting more power and the charger is giving it to you.

Much the same as setting the cruise control and driving over a large overpass, hill, or mountain pass. The RPM'* and speed stay the same, and the PCM lays on the boost to get you over the hump. This is why supercharged cars are so efficient and powerful in the hills and mountains. You don't have to rev up to the spooling rpm for a turbo. You get it when you need it at the lower rpm'*.

as i said tho, the highway was plowed and clean, it wasnt even wet, there wasnt any particular condition i can tihnk of that would be causing it, unless maybe the whole time i was driving against the wind, strong enough gusting couls accont for the flucuations yes?

Ok..fine..

New diagnosis: you are paranoid. It'* fine..relax

It could have been windy enough. 1-2 lbs isn't a real big difference

i swear something is acting funny in it, last nigh ton my driv eup to school i saw levels all the way up to 0 just to maintain 65 mph on flat ground, when it was normally -8 i just put in ngk tr55s would that make it worse? but why would it? if it somehow made a weaker spark than increasing boost would cause a misfire and retard the timing, reducing the boost and generally keeping it down, and if it made a stronger spark wouldnt it not have to use quite a smuh boost since it owul dbe getting a littl emore power?

It'* not the plugs. Boost will vary by load conditions all through the drive. Even what you think is flat might be a slight incline. If the boost goes up under load on an obvious hill, and it goes down when you go downhill or let off the throttle, and you get at least 7.5psi at WOT, you're fine.
