I do believe that anyone looking for a proper tune should weigh their options out and think through it logically. I think that AEM systems are wonderful and provide you with good flexibility for tuning of your application. The only hangup I have with a product like this is that it is a very complex system made from a company worth $20.3 million while a company like Nissan, worth $3,412 million (yes that is $3.4 billion), has spent more time and money developing a OEM product that works perfectly, than AEM is worth or has been in business for. In fact, AEM makes ecus for almost every application out there with their limited size and resources.
Maybe this is why Mazworx had to fix and develop a solution for something as trivial as the cam sensor pickup issues they had with Nissans and AEMs .. here is a link to it :

I certainly don't have to patch my tunes with products like this, because the ecu I tune was actually designed for the motor it is running, and not for a ton of other brands.

I think people that don't understand how things work (i.e. hiboost) tend to not accept them... hence the slogans in their signatures like "anti-rom tune" and "unstable maf tuning" ... which actually highlights their ignorance. I don't know about you, but I can't think of a single car ever produced that does not run a "unstable maf" sensor that is turbocharged from the factory. I too think I am a smart guy, but I know where my limits are... and until I own a multi-billion dollar company that produces cars, I won't call endless man hours and billions of R&D dollars "unstable".
