First, let me thank all of you fellers for all of the great posts I have read over the past year. Most every concern/question has been answered right here on this forum.
Now for my stats and question.....
I have a 2004 F250, 4" straight pipe, Bullydog Tripledog downloader (software is current), new turbo (oem), egr deleted, 140K miles, upgraded FICM.
When I get on it, NO SMOKE.... It used to blow lots of great black smoke, due to the tuner, while under heavy acceleration, now none. It quit shortly after the turbo replacement, and the egr delete. I had the FICM overhauled today because it threw the PO644 code. I have no other codes right now, other than the egr low flow code...
My concern is that the motor may be running too lean, however, I have tons of power, no hesitations, up or down. No skips, stalls, nothing. Starts very easy, every time, without fail.
Any input is welcome.....:dunno:
