I'm just trying to wrap my head around project plans and get some stuff laid out just in case I decide to spring on my temptation and build my car... So, since I plan on going boosted, and the stock ECU is kinda, well, non-adjustable, would it be worth replacing it. I looked at the AEM EMS-4 Standalone System, looks promising, so, would it be worth it and is it a good option or should I stay stock and/or look at a different system?
