Deleting the factory exhaust and egr system is needed to unlock fill potential in the tunext correct? Anybody want to recommend me a good vender with proven tunes.
I just bought a 2010 Duramax and looking for a good tuner for it. What's everyone running to get best results? I assume I need to get a turbo back exhaust and egr delete to do this right? Which vendor do you guys suggest. Thanks in advance.
