I am thinking of putting Boondockers NOS on my new 04 Summit Extreme, I have a lot of tunning experience but none with NOS. Is this pretty much a bolt and go system or is there a long expensive learning curve, i'm not looking for the absolute highest HP setup just a little bump when needed,

Give Holtzman Engineering (http://www.holtzmaneng.com/pctnitrous.htm) a look. As far as tuning goes this one seems like it would be the most consistent

I ordered a boondocker system for my 670, I think it should work pretty well.You make allot more hp's with the wet system ,(the boondocker is a dry system) but the dry doesn't form ice crystals. They told me it will produce up to 50 extra horse.I am not sure how this is going to work with the holz vari flow that I am using or the DPM that you have.I hope these questions will be anwsered when the kit gets here. I asked and they said they will work together. :D
