yes but look at what happens in camquest when you try a tunnelram on anything with alitle cam in it.. i get all sorts of weird numbers there is no way a edelbrock headed 340 with a fairly small solid roller makes a 50-100hp jump in output from installing a tunnelram making it a about 600hp motor.:banghead: never got that kind of weird numbers with the older desktop dyno(that refuses to install on a computer with windows8 btw).
