I have a 2007 6.7 that someone has put a proflow dpf delete on it with the small proflow tuner that plugs in under the dash to clear the codes. After you start the truck I am getting a P0472 (exhaust pressure sensor low) P2454 (diesel particulate filter sensor a pressure low) and a P0037 (02 sensor 1/2 heater curcit low). The truck exhaust smells rich, it smokes a little more that it should on a start, and has a slight rough idle. Any help would be great.

thanks

I am not sure about the flo-pro module in particular, but with other under dash modules you are supposed to turn the key on for about 15 seconds so it can reset the codes. I (as as i'm sure pretty much everyone else would) would recommend going with a tuner.

I do wait until the light stops blinking. So you think it is just a problem with the proflow and not with the truck.

How would it be an issue with the truck? You removed something and it is properly saying the pressure is low. You have an issue with your fooler so it would appear. What did you do with the downstream o2? Is it in a bung on the delete pipe or is it gone? Is the pressure module still under the truck and just the tubes unhooked? More info as to what is/isn't done to the truck is needed.
