I'd also recommend the Banks Big Head, although I suggest you get it from Dennis at

Just put one on my truck this past weekend. Previously only made 21 psi (with this old discontinued scmt that came on my truck). After the big head, made 28 psi getting on the freeway hard. It's got a MUCH stiffer spring inside, so it holds shut until it's supposed to open, rather than start leaking at 5psi and slowly opening to full around 21-22 like the stock one. Great product, so far. /ubbthreads/images/graemlins/smokin.gif

edit - you'll need a boost regulator of some sort also to prevent the SES light and defueling from the map sensor seeing 24+ psi. I'd recommend ITP's. /ubbthreads/images/graemlins/cool.gif
