Sry i know, once again i should be searching forums but due to lack of sleep, and time im just going to ask. I have an 07 2.0 T tiptronic...i read that the GIAC comes with an x or y chip...the lower performance going to the tip. Regarding the APR chip..does it work in the same way? or is it based on the octane rating, can i buy the 93 octane for my tiptronic?
