I have two choices here I can get both kits for pretty cheap. First is the dry kit which is a ZEX Nitrous kit #82011. Then the wet kit 10lb bottle, 75 shot jet unknown brand/kit number.(will find out soon). So my question is which should I buy/which is better? How hard is it to install? I'd like some tips before I buy them so I know what I'm getting into. FYI I will be on standalone when spraying so you don't have to tell me to get a chip.
