just so everyone knows vertex gets their motors from noyan. I personaly have never had work done on my car by vertex but i have spoken on the phone with someone named steve and he was very helpful. Also not all shops can afford to build $50000 racecars and race them at events. As for jason who fuckin cares if they don't know what a NX double crabtree shark nozzle is. You spoke with someone who picks up the phone not their master tech. Not everyone is as up to date with nitrous technology as you are jason i mean some of as have 2 do things like go to work and or school. We cant just sit around all day making sure there is no import performace product we havent ever herd of.
