Correct fueling in these motors is critical especially under high sustained boost!

Bad fuel injector(s) can destroy these engines in seconds! Cause most people keep pushing boost...thinking it will correct itself!

All Audi A3/S3 tunes are the same...cause they are all 'tuning' the same motors and same ECUs!

Some people are mad cause they blame IE for their engine failure...with nothing but speculation as proof!

I have United Motor Sports on my 2015 S3. Love it! DSG and Haldex too! Replaced injectors twice on that motor and finally replaced the entire motor for excessive oil consumption.

Upon disassembly of this motor I found leaking exhaust valve guide oil seals and 1 bad injector...

Audi went to a improved piston oil control ring on later built motors.

I have APR on my 2018 S3. Its typical smooth APR tune! DSG too.

Get whats available near you and fits your needs!
thx for the info. Is there a preferred set of fuel injectors for this car then or will it have to be OEM every time I get them replaced? What brand of injectors did you go with?
