Lots of boost on the line, don't hold it for too long or you overheat the box, and don't break your driveline hahaha.
I'm too scared to put a set of slicks on. Best 60 footer I've gotten is 1.9 as well.
Also "shallow stage" - stop juuuuuuuuuuust as the second staging light is lit up (when rolling forwards to stage). Makes a tiny bit of difference since the car can roll a tad before it is detected as moving by the equipment.
