^^^ Phil is right!

Cars with AVCS have the Intake cam sitting at a centerline of approx. 125* ATDC since the AVCS pulley is sitting in the most retarded position.

Cars without AVCS have the Intake cam sitting at a centerline of approx. 113* ATDC with the fixed pulleys.

This is most likely where the difference that people talk about come from. However in order to be sure where your cams are sitting at I would always recommend using proper cam timing tools so you know what you are doing.
