Sard 550cc, N60 MAFS, S15 T28, Enthalpy tune, ichiba manifold, TRust O2 divorced housing, cat delete downpipe (*i still think the sweet clutch plays a role too) and sounded sweet on the dyno.. sooo responsive. I wasn't really expecting more, I was just happy the hp and torque were very close together and it was consistent .. It performed at Desoto, we'll see if it performs in Miami..
