Turbo... Dealer has no good answer
So I have this re-occurring problem… I have posted about it before, no for some back story. I have had my truck in several times getting looked at… the EGTs under stock program are running up to 1000-1100f under moderate acceleration to 45-55 mph. I know that isn’t right. When I get of the throttle and roll back in the turbo is producing no boost and the truck doesn’t accelerate at all.
The dealer checked the EGR, the oil cooler and replaced the IPR (injector regulator Pressure) sensor, still having problem. I took the tech for a ride and showed him the issue. He said and I quote… Because I have 4 inch pipes all the way back with no muffler or cat the lack of back pressure is causing the veins on the VGT turbo to stay open. BULL SH)T. Doesn’t the right foot control the computer which in turn controls the VGT positions…? I have taken it to two different ford dealers here in town.
Any Ideas or FORD tech in NC who can help would be great…
