Default do i need a tune on stock injectors/fuelpump?

like the title says will i need to tune my car on stock injectors and fuel pump? i was just asking because i wanted to do my set up one step at a time. if i need to tune my car i will just get the injectors and fuel pump. i think you dont have to because the air/fuel setups are not messed with and if i do have to tune it can you please explain why?

sorry for the noob question, i feel stupid posting this, lol.

thanks

stupid question, are you goin boost? why are you buying a fuel pump and stock injectors?

to answer your question, you dont need a tune but will your car benefit from it yes. most defintately if you change injector size.

You want to buy upgraded injectors and fuel pump for a turbo project on your car now and are wondering if you will need to tune your car with these higher flowing injectors and pump on your stock engine??????

i think he means can he put the bigger injectos/fuel pump in right now before he boosts it..

no, youre going to need to tune it. gotta compensate for the larger injectors. just wait until you turbo it and tune it all at once.

Short answer: Yes, you do need to tune it. Your car wont run well on larger injectors and the stock fuel map.

You're not planning on running stock fuel system on boost, are you?

Should not be used in the same sentence.

The answer is no. Either do it right with bigger injectors/fuel pump and tuning first.. or don't do it at all.
