Smog Fix Question
Hey all,
Just took a smog test, and failed. What is needed to get the HC and NO down?
Here are the results:
HC CO NO
Max Measure Max Measure Max Measure
15mph 110 150 .71 .46 772 767
25mph 85 90 .59 .07 711 536
The car is a 91 RS with a L98 swap (stock setup) with a Catco cat, and cat-back setup.
What is needed to be changed to lower these numbers?

You could go with a new cat or have Kevin do a modified custom tune.
