Does anybody have an idea why my truck would be bogging down at wide open throttle. I get more boost and better acceleration at about half throttle than wide open. The truck almost seems to bog down a little. Could this be a fuel supply issue. It does this on any of the power settings with the Triple Dog.
Sounds like a fuel supply issue, have you changed your fuel filter lately? That would be my first step.
Yeah, sounds like rail pressure is suffering. The triple dog is pretty aggressive. Is it running different at all?
It runs fine under normal conditions. The coolant temp seems to be a little higher. Its running around 200 - 210. Other than that everything seems normal.
Could the bogging down that I am experiencing be caused by the computer sending out the overboost code. The MIL light on my dash came on today and when I read the codes with the Triple Dog it had P0113 Intake Air High input and P0234 Overboost. My peak boost shown on the Outlook is only 25 psi. Do I need an electronic boost fooler. I don't think the Bully Dog fools the ECM. Or does it.
Unless the MIL comes on every time it bogs down, it probably isn't causing defueling. I don't know for sure, but since the tuner's changing parameters within the ECM, I think they probably also change the acceptable boost limits in the programming so there's no need to fool anything. I'd start with the fuel filter, and if that doesn't help, have somebody put a scanner on it to watch desired vs. actual rail pressure to see if the actual is falling off from the desired. Also check your lift pump pressure to make sure it's maintaining as well.
