Excelent Question!!
Many of these types of upgrades are mostly hype and even those that are real can be deceiving because it's where the power is added that's important. You can add peak HP/Torque, but sometimes when power is increased at or near redline you can actually lose power in the mid range which is where you want it. You want to see an independent dyno chart with before and after power curves layed on top of each other, that way you can see where the differences are.
Bottom line, research before you buy.
I'm not saying this package is not a good one just that more information is needed.
