I actually just found where I saw that another member turned meth off because it robbed power in cooler temperatures. In the new world record quarter mile thread it says that 1sickM turned his meth off because off power loss. Hopefully he will chime in

Too much meth will drop power. It may be that in the summer you can run more but in the winter you have to drop some, assuming you do not have a meth tune. On my turbo E36M3, I run it for octane safety only with no tune and run only about 10% meth to fuel. I would agree it is possible it is costing me a little power on that car. If I dyno again, I may try with it and without it. The E90M3 with meth tune won't lose any power since the meth is replacing fuel and timing is advanced and air fuel ratios are altered.
