K the stock injectors peg out at 300 hp and the maf is good to 350. The only way the stockers won't keep up on a bolt on car is if you are spraying nitrous
and you need the extra fuel while spraying. This info is from experience.And do you have a tuner. You need it for those mods. Upgrading them however cannot hurt so if your getting a good deal on them I say go for it.
