Most guys run teh NGK TR6 plugs with a supercharger. Stock wires will work fine, or you can splurge on the high $$ Taylor wires. I would recommend boots on teh plug wired to protect form teh heat. You can do a compression check while you are right there, but I don't think that would cause a miss.

Go to an auto part store and ask them to read your codes for you.
If this only happens in boost I'm betting on the BAP problem. Sounds like you are going lean. It also sounds like the results of a bad O2 sensor but I'm not sure if that only happens when you are into the throttle or not.
Either way, go easy on it until you get it figured out.
Good luck, safe driving.

I appreciate all the input guys! I'm good at turning a wrench but am still in the learning process of diagnosing my own problems when they occur. A couple more questions... when testing the boost a pump, will just applying pressure to simulate boost cause the volts to change or does the BAP work off rpm's along with boost?

Also I just ordered magnecor wires and Koolsox from Lingenfelter. So it will be a few days before I get to try out new wires and plugs.
ok,

Sorry if my grammar is off or some sentences don't make sense. I do most my writing on here from my phone. It tends to make it hard to review and impossible for me to edit what I have written.

Found the issue, now what!?
I pulled the plugs and found the #6 cylinder electrode is broken off. It appears to be caused by heat maybe... What are my next steps? Is the plug tip still in there? Did i damage something, or did this break from detonation? The plugs that are in it are AC DELCO 41-110. The rest of the plugs looked really clean, almost to clean i think. The Grounding electrode is clean and almost a whitish Grey color on every plug except the broken one. I have no idea when these plugs were put in or how many miles were on them...

So i shouldn't worry about that little piece of the spark plug that is missing? It is the very end of it (the part you would normally bend to to gap the plug) that is broken. where would have it went other then sitting on top of my piston?

They normally burn off and are spit out the exhaust. Replace the plugs with a NGK TR6 or the safer NGK BR6EF non projected tip plug. Have the tune checked and fuel pressure at WOT checked for piece of mind.

There's are reason why it's torching the plugs. You said the previous owner had to replace part of the fueling system a couple of times...thats a red flag for me. Also the previous service may have stirred up some debris that's now affecting fuel filters or injectors.

The tuning shops i talked with today seemed concerned that I may have done some damage to that cylinder. Is this commen for the strap of a spark to fail on a boosted motor, I bought a set of TR6's and gapped them to around .33 +-.1. Should I just put the plugs in and try running it, or should I just skip to the expensive path and have the head removed and inspect for damage? As for the fuel system failing previously it was because the magna volt had failed from what I understood. The car had about 5k on it when the Maggie was installed and now has around 100k on it. The car was gone through and checked good for compression and leak test before I purchased it. It ran like a top until this happened..
