My truck has tunes from the previous owner that I really like except for the turbo scream instead of rumble at idle. He never put in a dsp 5 switch and just always changed them with the autocal. It was some random little shop in Cali that did them according to him.. would a cts2 work to switch in between these tunes?
How would I set that up, and do any of you know if a tuner would be willing to mess with only parts of someone else's tune?
I really want a rumble at idle, the speedo and odometer to be corrected for the bigger tires, and maybe a little different fueling because the truck spools much much faster now. I don't want to loose the ability to smoke a bit when I want to and fro. What I hear, none of the good tuners would allow that to happen because they are against smoking.
