just added a spearco. I have a trans plus so I can adjust the timing. Right now I'm at about 17 to 18 #s boost. The chip is burned at 19/17. I would have to back off the timing or add xylene to keep it from knocking without the intercooler. Now I have no knock and have turned the base timing up one more degree. So the question is do I start turning the boost up or advance the timing. I'm sure some of both. If I add race gas, what is the highest that I'd want to advance the timing?
thanks
