Does anyone know any reputable custom tuners in the OKC area for this motor. Also would be interested in hearing what other mods I should make prior to tuning. The only done to it is aftermarket exhaust.
I’m wanting to do a few mods to my truck it’s a 2015 GMC 2500HD (Denali) 6.0 Liter. Wanting to see if there is anyone in Oklahoma City Area that has history with custom engine tunes for these engines. Also would be happy to hear what other mods I should consider that doesn’t break the bank that would help out as well. The only thing that has been done to it is aftermarket exhaust and level kit.
