well, although I loved tuning the stock computer with the twin turbo GTO, there is one big advantage the BS3 and FAST has over it; they can both stay closed loop at wot. So you set the a/f you want and the computer can add/subtract to get you there, even under full throttle (although you do have to be within 25% of correct or so with your fuel mapping). The stock computer goes open loop past a certain throttle position/load, so your tune better be right. That, plus they come with a very good wideband to ensure the a/f you're getting at wot is correct.For n/a applications I really like the stock computer and a tuning system like HP Tuners. Even forced it works very well, just doesn't have the extra features of the aftermarket stuff like wot closed loop. nitrous control, etc.Jody
