I've only seen 2 scats dyno'd
Both were 420ish possibly 430whp
So to get almost 510whp isn't bad and more than the 60whp advertised.
Maybe Satera's dyno reads stock scats higher.
I had him quote me a procharger deal for my Jeep. Initially, I thought it was high until I started digging into what it would cost me to do it.
He is higher priced but he isn't out of the ballpark crazy either.
He is outside the Chicago area. Dealers shop rates are insane.
