You'll always get codes going catless no matter what if you have a cobb or another tune you can surpress them from popping up. I bought a DP fix to install a couple weeks out before I have to go for my yearly emission testing, it keeps the car computer in a readiness state which will allow the car to pass a DME test not a sniffer test. Hope this helps.

you would have to plug the o2 sensor into your new dps anyways, only way to get rid of the codes is to either run dp fix or tune them out with whatever you tune have ie jb4, cobb, etc

It will let you pass emissions but many believe it will hurt your fuel trims if you leave it in for an extended period of time. Here is a link

I believe the dp fix does the same same as the tunes do, suppresses the code, its for people who have aftermarket dps but dont have a tune and aren't going to get one, if you're going to tune the car then you might as well get the cobb now and same yourself the hassle

DP fix is to be used only to pass emissions. It will screw up your dme to run it constantly. Also why would you run catless downpipes without a tune?

As everyone else said, the DP fix is not to be used everyday only to pass emission.
To clear the code you need a Jb4 or Cobb
