Yeah exactly, and the reason why I was advised against piggybacks such as the Haltech interceptor on late model ECU's is due to their intelligent learning capabilities. Your basically cutting the standard ECU out of certain controls or signal bending.. id rather go a flash tune or complete ECU replacement if you can be assed.
I had haltech interceptor on my 03 sti, it took 4 hours to tune and I was told a flash tune would have netted better results. Not to say it still wasn't good.. it's just that the late model factory ECU's are pretty smart.
See how you go mate.
