People keep saying that this is the same engine as the S3. And whilst I do understand that it does have some of the upgrades of the S3 over the base GTI engine, is it really the IDENTICAL engine to the S3?
If it really is identical, then why are there separate ECU updates from the tuners like APR? Why do those updates take the Pirelli engine up to a lower figure than the S3/TT-S/Golf R ECU updates?
I've never really looked into it, because I had no interest in the Pirelli model (I really don't like the interior, and disliked that it didn't have several options that the regular GTI had), but I just believe that if it really were the S3 engine then it'd take the same ECU and have the same result in power... which it doesn't.
