I had my Roush tvs installed on my 2012 GT
about 6 weeks ago and have been having issues since day one.
The car is randomly throwing P0300 misfire, the dealer looked at it a few times but i never was able to get them confirm that they check the spark plug gapping and vacuum leaks. The only thing they did was to reflash the pcm.
Now....i got this wonderfull news that my Magnaflow x-pipe + hf cats were good for the scrapyard !!!
The cats have been on the car for only a few months, but strange enough 2 weeks after my supercharger is installed the cats are dead !!!
Tell me what you think from the pics below....1 side is much more damaged than the other.
Was this caused by the misfire or simply the Roush tune that doesnt turn off the rear 02 sensor.
Since i noticed that the car was misfiring i barely drove it so i,m surprised that a misfire could have caused this much damage so fast..
I tought that these cats were perfect for a supercharged car, maybe theyre simply made of poor quality components...!
