A compression test and a cylinder leak-down test as well. For what it's worth....my Sti SB with WRX heads and a VF22 put down 276whp/282wtq on a Mustand AWD dyno here in West Palm Beach, FL. Now, I know elevation is way off but here's the kicker......My boost will spike to 19psi and level off to about 15psi by redline. Oh, I've got Sti-Ra gears.
