Drove my truck about 4 weeks ago into Underground after hooking up with Newly about issues with my F350 6.0 all pissed that once again the truck stranded me. After 30 minutes of explaining Mike told me they'd get Scott to run diagnostics and let me know. Two days later we put together a list of all the issues that FORD never owned since day one. I told Mike that if they could not fix the truck I was selling it. Mike said they had seen my same issues before and guaranteed a fix. 3 weeks later I get my truck back and holy $hit. This truck has never ran this well at anytime even when it was new. Here's the list of things done -Bullet Proof EGR Cooler -Bullet Proof Oil Cooler -ARP Studds -Heads rebuilt and milled -Turbo rebuild -4"Down Pipe and new 4"Exhaust system -Blue Spring Fuel pump upgrade -Bullet Proof Water Pump -Fan Clutch Kit -New Injector -Complete Flush of Cooling System -EGR Valve -Serpent Belt -Trans Service -Dummy Plugs -Degas Bottle -Lower Boost tube -Edge Insight Monitor/EGT Probe -SCT 3015 Tuner I just wanted to say that Underground did what they said could be corrected and they stood by their estimate that I was given the first time. Thanks SP2 Mike
