I'm having trouble finding much info on this. First of all, I'm interested in emissions from an environmental perspective rather a legal perspective. I live in California, so no smog testing for me. I'd like to upgrade my nozzles but I know that requires EGR recalibration. And, I'm worried about the line in the FAQ that says EGR recalibration can increase NOx emissions by 40%.
So, in general, do bigger nozzles create worse emissions from our TDIs?
Now, in specific, I have a 2002 Jetta, 5 spd, B100, no other mods. What will going to Sprint 520s do to my emissions?
