Ok ever since I put the edge evolution in my EX the SES light has come on and shown P0475 which is Exhaust back pressure switch yada yada. I have tried three different switches on known good working trucks to no avail...I have also removed the switch AND the tube and cleaned both out to no avail. If I take the program out and return to stock then no SES what gives???? any suggestions?

TIA
Tom

Try our exhaust backpressure sensor eliminator. You are making a bit more backpressure than the PCM likes to see. Modified trucks can do this.

Would I need this if I have a 5" straight exhaust? I figure with no restrictions i wouldn't be making much backpressure... but I don't know if I'm thinking about it right or not. I get the yellow SES light quite often when running my Attitude chip. Maybe i need a new blow off valve. /ubbthreads/images/graemlins/shrug.gif
