I drive the $hit out of my truck in 20 degree weather and have not had one problem out of my Black Maxx. Good luck selling it.
I never puked in the first 25,000 miles I had the Spartan tuner. I daily drove the 275 tune from January until May of 2009. I then began testing the 310 for Matt in May and daily drove that for a few months. The first time I puked I hit 56 psi off boost on the interstate. I made 6 passes at the drag strip with the 310 tune and never puked once 5,000-6,000 miles into the puking issues. My heads came off at 67,800 miles (34,800 tuned miles) for an injector recall. According to my diesel tech, the head gaskets were not blown....so who knows
