Not aware of a lot of modders on AW. You might try AZ, but make sure you look at their commonly asked questions area or you will get flamed.

im not modding it to much just trying to get a lil more power out of it. Got a GAIC chipp, put on a test pipe on stock exhaust, and an air intake with an after market forge 007 dv. but what im thinking is that the fault code is because of the test pipe since the cats arn't there anymore. and the light came on after the test pipe install...

I guess I consider a test pipe a mod becuase you are messing with the ECU and it's expectations in terms of emissions. One of the things the ECU is looking for is specific levels and delta levels of 02 content before and after the cat. That is why you are getting the CELs. I know a lot of the conversation on AZ is about this sort of stuff versus AW conversations is generally just fixing things. Someone on AZ should have the combination of GIAC and spacers required to get the CEL to go out.
