I origionaly wasn't going to do a FET upgrade because I didn't have a sodering iron, or know how to soder.

Now reading the Tut, and currently doing the $10 Nitrous mod, I believe I can handle it.

The two things

1 - The tut I read replaced the FET's on the bottom of the Electronics Board - That's correct right?

2 - A 2x2 stack adds a FET on top of each one. On a 2x3 stack, where do I add the third one? Or does it not matter?
