swapping injectors

[MarcB]

I have kind of a dumb question here, can you swap injectors without any sort of tuning softwear? (just replacing the stock injectors with larger ones) Thanks, car is a 1998 TSI AWD.

No u can't . You need tuning software .. Ecm link !!!
What size injectors did you get ??

 

[Insane20]

At least get an afc or a maft. And for sure get a wideband!

correct u need to cut down the amount of fuel at idle low throttle etc and u can only go so large on a safc ive hear 550 maybe 600s I have a safc on 550s works great and a wide band is a must to tune properly

You'll need a bigger pump and AFPR to use bigger injectors, but no, you'll need to dial them in with software so you don't flood anything.
