Anybody have any ideas on who could tune a little cam swapped vortec. Still has the earlier 4 connector ecm. Should be pretty straight forward nothing crazy has been changed just looking for something to wake it up some. Thanks
Never seen one here in ga...did injectors and realized it wont hardly get out of its own way. Runs great otherwise just nothing out of the hole and extreme black smoke as it starts to pick up. Egr related maybe. Any insight? Thanks
