Cool

HI!... NACHO : Unless you are making more than 304H.P at your engines flywheel then the stock 19lb injecors are fine. You only need to upgrade to larger injectors if you are getting fuel starvation like me because you are making more H.P than the stock injectors can support. I'm stepping up to 24LB injectors next weekend. The fomula for figuring out what required fuel injecors flow rate you need is this. Take your FLYWHEEL H.P and divide it by two. Then divide that # by the # of cylinders you have (8). That will give you the size of injector that your particular engine needs. Hope this helps you out.
