Were you on a pull? How high were you revving? So many questions because I really want my motor to live and don't want to go too far. It's why I originally was going to go with a Hybrid instead of the S280. I would be limited by the turbo's capabilities and not be able to go too far. A deal came up on an S280 and I couldn't resist. I'm loving the power at 27-28psi on E30, but you know how us HP junkies are. Lol.
