Low Dyno numbers
Ive had my Z dyno'd twice and have put up numbers in the 435rwhp to 440rwhp range. This is way below normal for an automatic. I'm going to the dealership to see what can be done but something's gotta happen because I paid 60k for a 580hp car and right now that's not what I have. Any advice would be appreciated.

The car feels fine honestly but if it's a problem it may have been there since day 1. It's completely stock. I just hope GM doesn't give me the run around.

440hp? On a $60,000 car? Disgraceful. I would tell them to fix it or buy it back.

Dyno reading low? Not all garages jack up numbers for popularity.
I highly doubt GM would have shipped a car down big in the power department. Aren't they all (either engines or through the wheels) dyno'd before leaving the plant?

Did another pull and the car dyno'd at 483rwhp. I feel much better about that.
