Is that on insight or are you just talking about running it with the exhaust off before the dpf?

Don’t need any software for snap acceleration test. Unplug the exhaust before the DOC. You can find good video over the web on how to perform it. Done snap test in cut out only if you find excessive smoke.
For cut out you need insit to perform it.
