Stage 1 is about more than a simple HP boost, although on a Turbo Lite car the increase in HP is simply amazing! Overall driveablity is improved: better throttle response, etc.

My bonehead dealer told me it would take at least 4 weeks to get it, plus they told me that it included injectors and PCM for an '04 turbo. Wrong on all counts: I got mine in about a week from a dealer on the other side of the country! '03 cars get new injectors, PCM, and upper to lower intake manifold gasket. '04 cars get the PCM only. If you have an '04 you can install it yourself with a 10mm wrench in about 30 minutes. I know 'cause I did it. Yes, it works on a Turbo Lite. I know 'cause I did it.
