Default Long Tube SES lights

I have noticed that ever since I installed my LTs whenever I drive on the freeway after a while the SES light turns on and then I took it to AZ and they told me that I was getting an EGR flow trouble code. Really weird anybody have the same problem?

I have also seen a engine knock code come up...becuas eof the extra vibration coming from the longer tubes. Get it on a scan toll and have it checked out.

He did, I would think that is an easy fix if you have a friend with tunercat, or have a mail order tune delet that code for you. I think PCMforless can edit all the emmisiond codes and make them read "ready"

Somtimes those EGR Trouble Codes will throw the engine into safe mode, and then it will really run funny. I am deleting my EGR, so I have to get it completely tuned out.
