Hey all, I’m new to the board but not new to 6.0 problems. I have an '05 6.0, and had the EGR blocked, new cooler, new FICM and fuel injector all done a few months ago. Which required a new Ford flash. It threw a CEL, obviously due to the EGR block. I did not reprogram it, let it go & was going to get an SCT. I’ve been fairly light on the skinny pedal and didn’t tow with it until recently.
As soon as I started to climb a hill while towing, it went into limp mode & threw P0234. I pull over, shut her off, restart & its fine again,..... until the next hill, or I have to make a pass. Once I dumped the trailer, I went on the highway, hit a hill, got on the pedal & was able to get it to do the same thing.
P0234, from what I read, is over boost. I’ve been reading that its been happening in nearly all SD engines, stock or modified engines/programs. Some say its due to the new Ford flash being overprotective. I also read that there are only two tuners addressing the issue, one is H&S mini maxx..... but its over $1000!
Can someone please shed some light, verify or pull the bs card on what I heard?
