I'm working on an '05 NA Grand Prix. We've been having problems with low throttle KR and I have started removing timing to get rid of it, but with only a little luck.
I've set both the high and low octane tables to 10*, but I see as much as 30* when scanning. I did find a "Max Torque Timing" table, but HPT recommends not to mess with it. Would that be advancing my timing above what the main spark table tells it to? Here's a screenshot of the timing from our last scan. Everything above 1000RPM should be 10*.
