I just removed the AIS, installed PCIII and added the Thunder teardrop air kit. Thunder kit went on easy and looks great IMHO. I used girlzwarrior's PCIII map and it seems to be a good fit even though I have Thunder vs. BAK (map made for D&D slipon and the Barons BAK). It pulls like a mule and is smooth to redline. A pop here and there until it gets good and hot, but then it's clean. I'll check the plugs after a bit. Thanks for all the insight from multiple people on AIS and PCIII. It made the mods much easier. I posted pics in the gallery...B.
