Two turbo's is like saying two kits of nitrous is two power adders. Quit whining. And saying a liquid to air intercooler is a power adder is like saying that a fuel cooling cell is also a power adder.
Plain and simple Nitrous is a power adder and a turbo is a power adder. I don't care if youre running 4 turbo's or if your just running 4 kits. It's still one damn power adder. If you are running nitrous and a turbo then it's two power adders. Quit bitching cause boost > nitrous.
