    your car has 19 #/hr injectors stock, not 24s.......now that that's out of the way, larger injectors will be necessary once you get over approx 290-300 BHP......if you already have the 42s, might as well get a tuner to program them into a tune......larger maf you wont need unless you're over 400 BHP, but again, if you already have the 90mm LMAF, might as well get it programmed into a tune as well.....as far as fuel pump....well you get the drift...if you already have it, might as well have it all tied together and get dyno-tuned by a good tuner

    Your car has 21lb injectors. You will need bigger injectors and fuel pump. Focus svt pump will work. 42lb injectors may be a little over kill, but they should work. Stock maf is an 80mm so it's fine. You'll probably make 340-350rwhp with longtubes, which I don't see in your mod list. If you're doing heads and cams you should definitely get longtubes.

    I doubt you'll see 380rwhp with the stock shortblock. Check out this thread: https://www.modularfords.com/showthre...139918&page=14. This guy made 355rwhp on 11.7:1 compression with CMS stage 2's, stock intake, and through an auto. If the numbers were converted for a stick car it would be around 375rwhp. I think the trick flow heads increase the compression on the stock motor to 10.1. Paired with the CMS cams, trick flow intake, and longtubes i think you'll be around 360rwhp. SVT Focus pump is good to 400-420rwhp. 42lb injectors should be good to 450-475rwhp. It's up to you on the 90mm.
