Coming from a Porsche Cayenne with 500hp (and about 700lbs lighter), I was concerned that my pre-LCI 40i would feel like a dog. I've been pretty surprised at how well this engine punches above it's weight.
I threw the MHD stage 1 tune on it and now it leaves nothing to be desired. A V8 would be nice, but the added weight and reduction in fuel economy wouldn't be worthwhile. Being a torque-fiend, that's never something I thought I'd say. The B58 is a gem.
