Do you know what the stock timing is set at? When you set the timing to +10 do you set that at idle or revving? I watched a video on Youtube that showed that the timing changed when revved but I have no clue if that works the same on our cars.

Timing is set at idle rpm. Also note that as you change timing, the idle rpm must be adjusted as well. Factory timing is +4 at 650 rpm. The +10 must also be at 650.
