Low Boost after work done
I have a 2005 Excursion and I just had the motor pulled for HG, studs, EGR delete (bullet Proof Diesel) and oil cooler replacement, and many other replacements/upgrades. I had the turbo replaced with the Garrett Turbo for Ford 6.0L Power Stroke Diesel, GT3788VA, Stage 1, Non-Ball Bearing.
Once everything was put back together the turbo does not spook correctly and will only boos to about 15lbs. The truck fails/aborts on the self test. My mechanic has checked the y-pipe for leaks and we have replaced the VGT solenoid pigtail.
The truck is throwing the following codes. PO1000, PO407 and PO488.
I called my local Ford dealer to inquire about a diagnostic with them. They cannot look at it until after first of the year.
The truck runs great other than the low boost situation. I am about to pull my hair out over this one. Help and recommendations graciously accepted.
