Alright so I will soon begin building my 7M and I'm planning to make around 500HP. Basically I'm curious as to what I can do with the stock ECU. Is it capable of being tuned? should I go with something like megasquirt? Or a complete EMS like an AEM setup? I'm confused as to which direction to go. I'm going with a T4 setup with a FFIM, forged internals, the works. thanks for the help guys!
