But Wingmann, if you are looking for a good boost controller, I like the simplicity of my Greddy Profec B. Do some searching and you will find tons on bc's and bov's. Oh ya, I like my Turbo XS RFL Bov's too but they arent necesary for our cars because the stock recircs do a good job and some will argue they are just plain pointless. But I like them and I think they hold boost rather well during WOT shifting.
