Detune A E7 350 To Pass Emissions

Hey all,

I took my truck, 97 Mack Tri axle to shop on Friday to have a Smoke Test done. I was told 2 months ago NJ lowered the points from 40 to 20 for emissions. My truck threw a 31. So I am suppose to bring it back tomorrow and they said they would try and Detune the E7 350 engine. They said they would first check to see if the fuel pump diaghram was ok. If it was, then they would have to detune it to get it to pass. My question is what do they do on the pump to get it to pass. And will it hurt the performance of the truck. Dont know much about how they do that and the guy did not really offer any explanation as to how they do it.

Thanks
