I would recommend yopu talk to Gary Teague at GT Performance 909-982-8391, he really knows this stuff, and although he does some great stuff with whipples, he won't shove it down your throat. Also, if you need to use someone in NV, try Bill Dunsmore at Dunsmore marine, he's knows his stuff, and nice to deal with 702-293-1929.( he's in B.C. also)
