a fuel pump wouldnt hurt it, but did you tune it when you put them in or reset it?

pinks are NOT...no possible way...big enough for a 16g....and the pump is **** on the bugeyes
...replace that for sure, too

and you can not just throw parts on a car and not tune it


this is a disaster waiting to happen

I was planning on getting it tuned !! I just didn't understand why the car was chocking the way it was!! I just wanted to make sure that the injectors weren't bad before I take it to get tuned and I also have a fuel pump to install it

That's because you are a complete buffoon. Try reading the FAQ's and researching before you mod next time. You can not install larger injectors without changing the scaling in the ECU.

Your probably maxing out the pinks or at least close too it.....as for the pump....I had issues that little thing feeding my Td04 so I'm sure the 16g needs a pump upgrade

probably????

my p&p td04 @18psi maxed out the pinks

any decent tune with ANY 16g will max the pinks at stupid low power

PROBABLY???

NO 'probably' about it

No. An AP will only give you a limited amount of maps which include a vf39/vf34 for a stage 3 map. I dont believe there is a map for a 16g. That would be a protune. Your injectors are definately maxed out. I would suggest selling your 16g and getting a vf39/34.

I am surprised the car idles right. As others have stated you can not just put bigger injectors and larger turbo on the car and expect it to run right without a tune. There is a map for an FP 16g in the Accessport for an 03 WRX that uses 565cc injectors. Take a look at the map notes and see what it requires.
