I currently have a dps5 switch and about 700hp on mostly stock equipment. I drove truck with intercooler disconnected. Not knowing it would damage something. It smokes heavily now. So i already had collected parts; 68mm cheetah turbo, 200 over injectors and stroker cp3. A few yrs ago. Since the truck is down i wanted to install these parts but have procrastinated so long that my current tuner has closed shop. He says it was due to new regulations. So am i not able to install the parts at all. I dont mind having some stupid egr still active. Its a 2007 classic with lbz. I dont have def or other new bs. Does anyone know someone to write tunes? I do have the handheld unit the old tuner was able to send me tunes and i downloaded. But he still has my factory tune. What can i do? Thanks
