It depends on the days but I'm in SoCal so mostly dry and hot. But this manifest has been going on for the last 4 months or so (70-85F mostly). I just haven't gone to the track much for those months though. But it has been pretty same every time. I re tune my engine like everybody else every time I go there but I didn't pay a particular attention on HSN doing that so I don't remember if it was better at certain HSN.
I used #7 Nova plug and then changed it to #8 1 month ago but it didn't make any difference. Maybe I tend to set HSN too lean. The plug is not very dry but the coil is gray when I take it out and I know it is on the lean side.
I'll just make it rich a bit to see.
