I want to put a standalone in my car but I am unsure of wich one to buy. Can anyone help me decide which are the great options. I am partial to PFC and the AEM EMS because they are easy to install. Are these good systems and wich would you recommend. Also, what books or articles can I read to start learning how to tune my car. THanks.

for an fd the power fc is a great choice, it plugs right in and the car starts and runs better than stock
