Wouldn't say its more "powerful" if it can accurately tune it can make just as much power as the next. No its not as easy to tune as V3 but its ok if you actually know what you're doing. If you get full V3 and not the lite it can do 95% of the stuff AEM can do including everything mentioned above. Its really all in what you want to get. $1,500 for AEM, $500 for V3, or $400 for Maft-Pro.
