Message: [QUOTE="Mwilbur516, post: 392908, member: 784"] Ok, I wasn't clear enough. I meant that there is something built into the ECM not allowing it to make higher boost numbers. My truck (along with several other truck) are running into the same issue with other turbo's. I even started a thread about it a while back. This build isn't the only one running into this problem and I don't believe the turbo is at fault. Maybe the injectors are fueling heavy, if so then the tuning can be adjusted to lower EGT's, but I doubt that will affect max boost psi. Sorry if I wasn't clear that I don't think it's the Gearhead tuning, I think it's something written in from Ford that effects several of us. [/QUOTE]
