Yea what he said Rave(owner of twisted diesel) is a personal friend of mine and he does great work. I just got a CUSTOM SCT tune from him that was made for the mods on my truck. And trust me you want a custom tuned to fit the mods you have because if it aint right your egt's will kill your motor. You can also visit him @ http://www.twisteddieselperformance.com/
