I have no idea how to tune his car... so I'm not going to be able to make any specific recommendations. My personal expertise in 'passing'
Aircare has to do with GM 3800 engines. I have something called Powrtuner which plugs into the PCM and can disable codes, change timing, etc.. so the fact that I have a gutted cat, no rear O2 sensor, non-functioning EGR, etc... all things that should cause it to throw codes and instantly fail Aircare... well, they're no longer active and therefore not an issue. I re-flash the PCM to a stock ('ish) program to pass Aircare, which cranks back the timing, makes the car run like shit, etc but it works. The rest of the time, I run my regular tune.
Frankly, it sounds like the OP doesn't really understand why his car failed (hydrocarbon count almost twice the maximum allowable), so without a proper understanding of the problem, band-aids such as throwing methyl hydrate in there, new plugs (which were just changed), or a stock intake... or an exhaust silencer?!?.. I really don't have much faith in the OP's mechanical ability (sorry OP!). He's looking for some sort of quick fix. If I were to suggest pulling timing by cranking back the timing in the ECM, I don't think that he would have the necessary equipment or knowledge to do so. A local tuner shop would, however. There are some great tuners that are RS.net sponsors... go there.
