Well, where do I start. I would advise in doing something else in airflow or density before going with an intake---preturbo. I am not saying that the AEM won't do any good, but, you won't notice any big change until other changes are made. If you are looking for more horsepower, more (or different) fueling is needed. Depending on how far you go, you may get better mileage. I know from personal experience diablosport powerpuck is a good buy, not much for improving mileage for me, but, you can tell the 50 horsepower hits the ground. If you are more interested in EGT's and power is secondary, there are a number of things you could do, including the intake (it has been proven to lower). I will say that the more power you want, the more you want to look at exhaust, before and after the turbo, and the intake arc of the manifold. I hope I have not confused you w/the turnaround I have given you. I will tell you that the diablosport is about as much as the aem and is at least as easy to install. I am not trying to pull you away from aem (i personally have a lot of belief in their product--because i own 2 of them on my truck and honda), but, you will notice it does more for you after you add either more fuel or more airflow.
