You'll feel like a smooth pimp when you get it all put back together and test drive it for the first time. It really is a night and day difference. Once she gets to about 3,000 rpm's, it's incredible how much harder it pulls to 5,500 compared to the crappy NPI intake and cams.
That's my favorite thing about doing my own mods. It's very rewarding when you install it yourself and get to enjoy the results
