What are your mods? That will depend alot on what type of injector you want to use. Most FC's with mild mods (stock turbo, exhaust upgrade, intake upgrade) benefit from keeping the stock primarys and upgrading your secondary injectors to 720's. Of course it always helps to have some sort of way to monitor your EGTs, or AFR's if you upgrade your injectors.
