No its reg is in a exempt area, and I love the holley, right now its stock besides vent flutes so I still have to put a modified vent tube and spring loaded needles and seats, but for what it is I have had no problems getting what I want from it. I have used holley for years and when you mod them for offroad they work great, the trick is when crawling is lowering the fuel pressure as not to overflow the floats, most of the time I use 2-3 psi when crawling, also there is antislosh foam that you can put in the float bowls to help as well. I recently saw this little deal that bolts to the powervalve and changed the jets to a low center feed and prevents them from being uncovered, Ill see if I can find the link.
The one think I learned recently is using a wideband O2 makes this so much easier and cut and dry that this truck is the best running carb vehicle Ive had. If you don't have a wideband get one. the AEM uego is 164 bucks and worth it.
