Hopefully next month I will have gotten my FMIC, a/f gauge and retune, which should put me at 340-350. Next year im planning on getting a fp green or dom 2 or some stock frame turbo( only because i don't wanna wait till 4500 rpms before boost). What im wondering about is will i really need to get new injectors and down pipe? And will i need anything else? my goal is a 400 hp DD, the more i read the more i get confused so your input will be helpful so i know what to save up for.

 

What size is your current downpipe?

 

Dp will help with spool and will give you some power for the price. as of injector wise it depends how much power you want to make. im sure your tuner will go over this with you.
