Has anyone with a Supercharger ever pass obdII emissions?
 

Supercharger on a V6 LLT with longtube /hi flow cats (Illinois Chicagoland Area)

I installed mini cats / extenders but not sure which codes enabled or disabled can prevent the catalyst monitor from readying up.

Right now I get p0102 because of the s/c

I pass here in NM, though I have shorties with stock cats. My tune has the rear O2 sensors disabled.

I pass every year here in NC.

SS's have no problem but the v6 tuning does.

P0102 is a MAF sensor code. Do you have a blade style MAF card or does the V6 utilize a MAF that is molded into part of the intake tube?

Blade for sure with the Overkill kit
