Egr code

[jbougher444]

I was having issues on a road trip last year and ended up leaving my 04 6.0 at liberator in carlisle PA last year.. they put in a delete kit and 2 days after i got back home to jersey the light came on..They kept telling me to keep driving and it should go off..Well time went by, i got used to it, truck runs ok, but light is still on and im up for inspection soon...Any help would be greatly appreciated, Thanks!

From what I understand you need a programmer to turn the CEL light off. As soon as I put my EGR delete on the p0403 and p0405 codes came up. I put the SCT TSX on with custom tunes from MPT and the light is gone.
