So new to all this and kinda tired of having to wait on files from tuners, with that being said I have all the unlock tools and auto cals and bypass cables to do everything, I would just like for someone to chime in on how to even start to tune a let's say a truck that has already been tuned and had the exhaust cleaned, but tunes are crappy? What do you adjust?

Secondly if you get a stock truck in and clean the exhaust what do you adjust afterwards? Do y'all have the basics yall run through for this process?

pm me if would like to talk privately. Thank you

I'm not sure what exactly you mean by 'exhaust cleaned, but tunes are crappy'. Generally speaking you're going to be swimming in mud for a while trying to work yourself out of somebody elses mess unless you have some idea of what part of their crappy tune you'd like to change. Use the chisel where the previous sculptors work is worst.

Is there maybe some particularly crappy part of a tune you'd like help with?
