I use the B&M Hammer which is a ratchet shifter so I can only go one gear at a time which makes up to neutral impossible. It's not a huge deal I do run an o2 sensor in the collector that records the entire run and that has helped tremendously in tuning but my next objective is to get each individual plug reading the same which is a great perk of EFI.

For what it is worth ATI doesn't recommend it at all - even with a Clean N. Once for a plug reading, okay that is cool. But the guys that do it ever pass are just reducing the life of the unit. In the pits, on the track, doesn't matter. When the engine is stopped, the transmission pump is not moving any fluid to lube the gearset that still being spun by the driveshaft.

I've been told in a TH400 clicking it into neutral causes the driveshaft becoming the driver and the way it multiples will cause one of the drums to spin to 20000 rpm+ and it can go boom.
