It took restraint not to move right to the Boss manifold, but after establishing a strong baseline, we swapped only the throttle body. It really is the ultimate remove-and-replace job. Just remove the induction tube or CAI, unplug the throttle body's electrical connections, and remove four bolts. Do it all in reverse and your new throttle body is home. In our experience, the car needs one start up and shutdown sequence to learn its new throttle body; after that, it idles like stock.
