I'm no expert on dynos but I heard dynopacks dyno 6% lower than the rollers. Again, i'm no expert. Maybe someone can shine some light on this... I actually thought I wouldn't break 450 hp.
As for the gas mileage, it says 21.4 on my guage but i am pretty sure that's wrong. This beast uses a gripload of gas but it is a small price (large?) to pay for the power and overall awesomeness. I constantly get a lot of compliments on how great she sounds. GTM did a great job.
Lastly, the little dip/spike might be when the SC kicks in? I dont know... I am only assuming because of my baseline is around there
