Have a CAI also, and for all I know it only added noise, but I'm cool with that. TB spacer is a waste IMO.
Hes pretty much right. I have a flashpaq, and I can feel a little bit more power, but not much. The throttle response is awesome now, and the tranny shifts way better than it did stock. But this is gonna be the case with most any programmer. Theres not much extra power to be had by these engines because they use a speed density system which uses a MAP sensor instead of a Mass Air Flow sensor which can actually measure how much air is going into the engine. A MAP sensor just measures vacuum in the intake manifold and the computer uses that to determine how much fuel to give the engine from a predetermined set of tables. You can put a cold air intake on, but the computer can't really tell you have more air entering it now.
