Correct me if I am wrong but doesnt the The boost level vary with different weather conditions.
Another. Words the boost may be lower than 12-15
Also if the traction control is on it will feel much slower
I would recommend taking traction control off?
Check how the oil looks,
Have them put it on a lift if U are serious about buying and look underneath
.you c as n pretty much look throughout the car and see if it was taken care of.
When I looked at mine a couple months back you could tell the previous owner took extremely. Good care of it.
I also looked at another ss when I was there and looking at the outside and inside you could tell the previous owner did not take much pride in owning their car.
How many miles are on the ss you are buying.
I myself would not buy one unless it was gm certified with a 12000 mile 12 month bumper to bumper warranty.

I'll go out on a limb here and guess that bigjack is wondering if there is a direct correlation between varying weather conditions such as barometric pressure and the amount of boost achieved.
Well yes there is, but in a motor vehicle, the effects of varying barometric pressure are almost non existent. But if you really want to split hairs, a deviation from a "standard day" which has a nominal barometric pressure of 29.92 inches of mercury, to a day with a high barometric pressure say 31 inches of mercury....you'll see an approximate gain of 3-4% in boost.
You won't feel 3 or 4 percent in your "butt dyno", unless your buns have been calibrated. Where the weather can be beneficial to a boosted vehicle is on a nice cool and damp day, the lower intake charge temperature combined with the higher humidity can forestall detonation allowing a more aggressive ignition advance....and a wee bit more oomph!

sorry about that
Looks like my auto spell correct was working overtime.
My question was that I believe that the boost varies.
another words if the air density is high the car may actually boost lower due to the car restricting the HP output to a certain limit from what I have read on the SS cars.
If that is the case then these cars stock would be great for bracket racing.
