Which Injectors?

**Kittrell** · 08-25-2008 08:23 PM

I am going GIAC 1+ soon enough and I am curious if anyone has done a comparison with all of the available injectors.

Siemens
Genesis
Bosch
Dealership/Audi

Whats good?

The GIAC FX (1+) was developed using the Siemens so they should be fine. The Genesis 380 is closer to the Bosch 386 (TT225) injectors as they both have a dual cone spray pattern. Clicky click Personally I would recommend the Genesis or TT225's over the Siemens because of the OEM type spray pattern. I would stay away from the Bosch 380's. They have a single cone spray and there have been numerous reports of hard starting issues in the cold with these.

I just popped in my Genesis injectors and got the GIAC injector program from AWE last night. Feels like getting chipped all over again, but the fuel consumption you reallyyyyy have to watch. It's a pig if you get into boost...which is real easy to do now.

So it looks like am going to get the benefit out of the TT or Genesis units. Thanks guys, I'll probably just spring for the TTs then. I wanted to make sure I wasn't just paying more for a name.

I have the Siemens and they work fine, no issues what so ever...

QFT! Any chip and the associated fun kills your mileage. I went back to "Sunday" type driving one night and got 33+ MPG; haven't seen that in a while.
