I'm buying HP tuners soon and I want to know where i should start with my tune. Never tuned before but I want to know some of the stuff I should change to make my setup run the best it should. 99 SS M6. 04 Z06 longblock with SLP headers intake and flow pack. Stock injectors, fuel rail, MAF, coils, MSD wires. And also what do people mean when they talk about tuning in speed density. These may sound like stupid questions but I don't know what I'm doing when it comes to working on computers
Thanks
