i guess this should probably go in the tech section or elsewhere but i want some answers. So i had a 2.5" offraod DP installed and of course i have an SES code (P420 catalyst inefficiency). gee, i wonder why 
? Anyway, i need to remedy this ASAP without buying an aftermarket PCM. but im not finding an O2 sim ANYWHERE, at least not one that will work on 04+ GPs ( I have a base level 05 GP). First off, i dont see why the O2 sim for 97-03s wouldnt work on my car, its the same exhaust setup, so what tha....In fact, i dont even know where to get an aftermarket PCM for 04+ GPs but thats besides the point, i want to avoid going that route for now in the interests of my bank account...wheres the mods for the 04+ models, wtf!!!oh yea, thanks for any help guys!
