    OEM+ fuel injectors ?

    Was thinking of having my injectors serviced by Race German. But before I do that. What direction should I take when it comes these injectors? Is there a OEM+ injectors that I should upgrade to? Also, something that I don’t need to tune and mess around with. Something to install in the morning and drive in the afternoon. Appreciate all your input!

    You can't go to a higher flow injector without messing with the tune after.

    ... and unless you're making a bunch more power than stock (FI), not really any gains to be had.

      Does anyone have any experience with Race German's injector rebuild service? I bought a set of detent pin tools that they make a long while ago, and was very pleased with them. My brother however, bought an e30 touring on BAT from the owner of Race German who supposedly did a lot of work on it himself, and that car has been a bit of a basket case haha.

        I quit buying from Race German when I used their SS VANOS line that came with these cheap banjo bolts - could never get it tightened right, turns out it was inferior metal and yielded and necked!

            Yeah, I replaced it with an OEM bolt from the dealer and wouldn't you know it, it worked perfectly.

              you sure you want to be running that vanos line? Updated factory line, with the additional mount point, has proven to be pretty faultless...

                Went with the grey Audi TT Quattro injectors.Pretty much plug and play from the physical measurements and connectors. However I did have to change the tune.

                  unless you're using FI, best thing I'm aware of is to send them off for a rebuild and use good fuel going forward.

                    These are the guys that I've gone to for the past decade plus with multiple different builds. Had them clean my M3 injectors a few years ago, no issues.

                      It's just a simple scaling of a constant? It's tempting to go this route but don't want to create any issues.
