Little lower than I would expect. But it may also be the high altitude.

Its my unrstanding that there is some kind of formula to calculate how much HP is lost per 1000' of altitude. I cant remember the figure per thousand ' though......anyone know??

HP LOSS= (Elevation x 0.03 x HP@SEA LEVEL)/1000

Works out that 3%(0.03) times your HP= loss per 1000'

I don't have a sea level number for my car so my guestimate is:
My car dyno'd at 376.1 HP @ 2320'
376.1 x 0.03 = 11.28 HP loss per 1000'
Therefore 11.28 x 2.32 = 26.17 HP loss @ 2320'

So supposedly at sea level my car should dyno @ 402.27HP. I hope to dyno it at Jeffs this Summer so we'll see......

Considering the altitude, I'd say that is probably typical, all things considered.

I lived in Bailey CO (8500 feet) and I could tell a significant difference just between Denver (5280' amsl) and 8500', to say nothing of comparing my 95 LT1 coupe at 600'!

Altitude is a big concern for me and my plans to move to CO to live. But, I guess all things being relative, performance will remain the same, compared to other cars (except for turbo or SC cars!).
