Been there done that!
My EJ255 lasted 126K and gave me 150psi compression and 10,10,10,5% leak down, so I figured it's worth a try to make big VF power or bust. I then pushed it a bit too hard after a Junior E85 tune making 450 WTQ & 360 WHP. My stock STI clutch hated it anyway. Not that Juniors tune was bad, I'm not saying that at all but you gotta pay to play as the saying goes
