When is a good time to have a water meth injection put in? what mods should be done before this? it seems like it is a cheap way to get some xtra ponys
Sorry to HIJACKWater/meth is a good power adder, it will give you about 40hp at 40% meth. Dont go over that if you value your rods and motor.
Wait on water injection until you have done other things first.
