These guys are right, if you want any more power than stock, you'll get a little smoke most of the time, and higher EGT's as well. It takes fuel to make power, and more fuel means more heat inevitably. However a good EFI Live tune can get you some very nice power and with none or at least very little smoke. And it will have better driveability and smoother shifting than the PPE, and definitely better than Banks.
