In Dinan's defense, they do claim that their maps never put down good dyno numbers, as the fans typically aren't big enough to keep things cool enough for the maps to allow full power (so there's apparently a more sophisticated temperature control function vs. the JB4...which just has cold engine protection).

People claim that in the real world, the whp is much closer.

Not sure how much of that is true...but I'm sure the OP can shed some light on it just by driving his car around. It should produce a dramatic difference in power.

Like, people generally let out a chuckle the first time the dig into a tuned N54/55.
