Hey whipplecharged...I was only getting 5lbs. max when I first installed my Whipple last November. I thought that my bypass was opening to soon so I called Steve and he suggested that I purchase the smaller pulley to see if that is still the max boost I could get or if it was the bypass valve. It now goes to 5 1/2 to 6lbs. max. As you can see I have headers and exhaust. It sounds like that is something that is taken in to consideration now when you purchase one for the H2. As I mentioned in a previous post overheating has never been an issue even in my extremely hot climate!
