Injectors, pump and rails at the same time?

I'm mapping out what mods im planning to do come the spring time (and my new apartment with a HUGE driveway and i think fuel delivery is going to be a good place to start. I am also going to be putting the cobb accessport, HKS hi-flow dp and full exh. With these mods, my gut instinct would be to increase the flow of fuel to compensate for the higher power/ tq output. Should i do the injectors, pump and rails at the same time? Is there any specific order that i can / should do?

You don't really need to touch the fuel delivery until you upgrade to a bigger turbo

You're gonna need EM to control bigger injectors.

Dude if I were you i'd scrap the fuel delivery for now and definitely go with TB exhaust and down pipe first. Then do Cobb AP. Trust me you'll love it.

If your planning on going with a bigger turbo in the future and you're getting a good deal on this stuff then definitely get it, just don't install anything until you need it. You should do a turbo back exhaust the EM then you could upgrade your turbo and fuel delivery.

Try to stay away from the HKS DP too, it's not that great. Go with a bellmouth design. Doing an engine mangment will fix the full issue's you might have with the TBE
