Thanks for the good info. I have seen the det cans and that was my second plan if the knock sensor did not work out.

So how do I go about setting up a spark table? I have my fuel table set up pretty well just needs to be leaned out in boost but the spark table seems to be a little more complicated. Is there a basic spark table that I can use that is close to the stock table?
