I recently had a nitrous kit installed on my 09 Summit XP. Other wise all I have done is an SLP can. I figured I would notice a huge difference. Many people told me once I hit the little red button...wham...instant power. Well after I tried it out a couple times just through a field behind the house....I don't really notice much at all. I never held the NOS on for too long, probably 5 seconds. Is this not long enough to notice a difference or what?? I believe it's set for for an extra 20 hp?? What's your thoughts for those who have nitrous on their sleds. Should I have just done the clutching, and gears??
