Surprised to see this comment. I am leasing a 430 GC and had similar buyer's remorse. I also have the JB+ installed but I've never test driven a 440 so can't compare. What I can tell is that I am already very much used to the power even with the JB+, and I drive it in Sport mode basically always.
With the JB+ is it really that close to the i6 engine already??
