It will not do anything since you are not tuned for it. So do not do it!

What hes saying is that you wont need bigger injectors with just A CHIP. Youd need a bigger turbo for you to need bigger injectors.

A chip definitely makes a difference in performance; however, all B5 chips are tuned for stock injectors. Please take a look here, it should clear up many questions.

What they're trying to tell you is that, your chip is currently/probably tuned for your current injectors. If you want bigger injectors, you will need a tune/chip that is tuned for the bigger injectors.

Whether you need new injectors with a stock turbo is a whole different discussion.

*if your car is properly tuned for your current setup, any change to the engine and some of it components will need a re-tune/re-chip, to either maximize gain of the new part or just to make the engine actually run.

Aaaand as I said earlier there is NO off the shelf tune for the B5 A4 stock turbo that upgrades injectors.

APR stage 1+ for AWM uses larger injectors. As does the revo 2+? Not sure on the number revo uses. Fairly certain unitronics can as well.
When I looked into it years ago, it seemed as if you also needed ALL the supporting mods to run 1+. Not much of an increase for the $$$
if you ask me.
