I recently installed my Bosch 310cc injectors on my A4 and then the car hardly wanted to start so finally someone told me to put a 4 bar fuel pressure regulator.. this helped a lot but it still does not start as it did with the stock injectors so I'm starting to think it was useless? I have a GIAC chip... how big are the stock injectors and was the upgrade worth it? I don't really see a perormance difffernce Thanks!

This may sound stupid but what do you mean by run rich? Can I just go to a tuning shop and have them tune my ECU so that I get more power out of the injectors?

Even with the K04 turbo upgrade the stock injectors work fine (235HP + or - a few HP)

Upgrading the injectors AND a different chip results in a 247HP K04 upgrade.

See AWE's website:

I'm not sure who told you the injectors were good to use, but in my opinion you don't need them and as you have experienced, they don't work better than the stock units, even with your GIAC chip.

I would take them back and save the money.
