looks like it has a lot of attention in the 340I community because their B58 has less power to begin with and adding the MPPK for 2K+ is not worth it when you can just buy the MP Flash.
our M240 B58 engine tune is about the same as the MPPK tune... not sure how much power we can add with the MP Flash but would be interested.
@nugget posted his results but I need more info.
