If this is the video I am thinking of, it is at atco track which is the best track in america supposely. The track itself is worth 4 tenths is what everyone says.
Kinda funny how you went a fluke of a 10 last season and this season after doin more to the car, you go slower.....Way to wrench....
A car that makes a 10.999 pass with not one single other 10 sec pass to back it up is hardly a 10 sec car.
Only help I can give is like Rob said, bad ground, relay or I heard NOS soleniods dont like heat. You should just get some NX ones that way when they go bad, you can send them back to NX for a full rebuild for free.
