. Took it back to the muffler shop where I got my catalytic converter so they could check it out as i thought that was my problem they told me that my D: is running too rich and that it burnt my Cat again this was within a couple of days of installing it and that its not covered by the warranty and I need to pay for the replacement but he recommends I get the fuel mixture checked out before installing a new one. OH and just to top it of it wont pass smog not because a bad cat but because it has a supercharger

From my experience of owning a forced induction vehicle (85 turbo shelby), it is always better to run colder plugs for forced induction engines. You should not have to worry about the heat range since you are already increasing the compression ratio by several factors, it will generate the the extra heat in the combustion chamber.
Forced air induction engines runs much better with colder plugs for those that likes to run their engines in the upper rpm range

The colder plug retards the timing to burn latter. This avoids pre-denotation due to added compression lowering PING. Complete detonation will exceed into advanced timing due to the compression. Also octane would help but I think you would have to run airplane fuel to retard timing. This is why most racers utilize both.

Im not busting ***** but a couple days on a new cat? Im sorry but i cant see that happening. You live in CA right? Superchargers are allowed
As loud as that thing had to be with a straight pipe, you passed? Regardless of the payoff... I call BS too.

In Ca a licensed/registered motor vehicle shop "cannot" turn down an emissions inspection, esp to a supercharger. They would take your money even if they knew you would fail. Now i can understand turning you down if your pushing a cel or something isnt legal/safe on the vehicle(shop liability). I know im def coming out as a ***** but im not trying to be. If the issues are so bad that somehow the cat got burned up in little time, your engine would be catching damage aswell. I'd park it till i knew what was hapening.
Quick question, now that your straight piped and suped, what Cel you throwin after reset?
