Thread: Will an aftermarket tuner such as a BullyDog allow me to delete code P420 from PCM?

Bully Dog 40402 Bully Dog WatchDog Economy Engine & Vehicle Monitor Will this allow me to remove P420 from the PCM forever or will I have to buy an aftermarket PCM to accomplish this?

dude just clear the code go to autozone or some other place that has a code reader

no, and you dont want to delete it permanently either. The code comes up for a reason...

Lol.^^

The bullydog won't delete it. You will need a tune for that.

I want it deleted due to a high flow cat. Do you recommend any tune or PCM? I checked 3800 performance and ZZP both don't say that it will remove the code. Probably my best bet is to call them but I wanted to see if anyone has done the same already!

Just google spark plug non-fouler trick. ~$5 fix.

He has a 05. According to ZZP won't work

Bingo. Exactly what I did until I send my PCM back to will for a retune.
