SCT 3015R and ***/cat ******. High idle

[Cantbuytime]

I have been running that sct 3015r for a week with the EGR and *** turned off in the tuner using factory exhaust and it's been running fine. Today I made my own ****** pipe. I remove the ***, cat and mufflers. Now the truck is idleing at almost 1000 rpm. Read a few threads that the EGT sensors needed plugged in but not installed The front sensor is still in the factory spot. The rear 2 have no bungs anymore. So I plugged in all 3 sensors and the pressure sensor. Still idles high

What to do next?

One of your sensors is bad then. Set requires all the sensors to be plugged in. I even left the pressure sensor plugged in and had no issues.

I had read that only the rear sensor would make it idle high? Is there any truth to thatl?

So just replace the sensors and it should idle down on its own. I don't have to reset the computer or anything?

i would buy one new sensor and try each one individually until you find the culprit.

Ok. Thanks for the help
