Thanks for the specs. Smokem, is the butten you refer to the jet or orffice setting on the spring or the entire assembly that screws down ontop of the DV? Sorry dont know all the term.ology yet. either way wow, there looks to be a lot more fuel gained them from some simple machining, if the stocker is .025 and the lines are .078. Who all is set up the hone them, being that im nearing done mounting this huge charge air cooler, maybe i could try the enlarged holders? And poss. even try the ol full cuts again, hope so these temps have been a bear to get under control w/o a cooler. Thanks Ryan
