well AT guys can maintain boost through the shift regularly, and lots of high HP vechiles are AT. if you remember the lingenfielter (sp?) corvette that they pitted against the f-18 or whatever...my dad knows the guy personally and said they were origionally gonna do it in a standard tranny car, but after a while they could not find a clutch that would hold the power....even custom clutches...and i guess some people like them for a daily driver and in traffic and such. me personally im a MT guy all around but auto does have its advantages.
