what im thinking is that when its cold the timing goes up, which is why in the winter i see almost 18* of timing and only 13* in the summer. im thinking this is where my knock is coming from, as well as not being tuned in any other aspect besides my fuel trims. im sure if i got a good tune on it as it sits right now without the intercooler that i could run the 3.2 knock free 100% of the time.
