Default Use the OEM Audi TT225 Bosch injectors. You must have the correct ECU software to run these parts!

With engine output upgrades, the fuel pressure/regulator is not usually changed or modified on the B6 due to the design of the fuel system.

Default get the injectors that are designed to run with K04 programming you're running

if you don't have K04 programming...

STOP -- get the right software, get the injectors to match, and see what it says about fuel pressure. Generally, you're not going to change anything on your B6 because of the returnless fuel system and constant rate FP.

Default With either choice, you will think that you are driving a different car!

The TT225 OEM injectors work perfect with both of those tuners products.

APR does not offer K04 software. At least not yet.

Default There are also other tuners that offer the software for the K04,

Giac, MTM, Dahlback and I think AMS offers it too.

I would suggest going with Revo over Neuspeed.

STFA for more ideas/info.
