Im running a bone stock b18b and i just put a 70mm BBK T/B on and yes! i get AWSOME Throttle responce and i dont know what else it is doing but i can tell you that i also pull alot more off the line. s oit uped my tor. also. my over all top end has gone down a little bit but thats alright with me. I blocked all vacume lines going to the T/B and just ran the Map from the manni itself. Works great!
