Hello Everyone,
I have a 2010 Suburban 1500 with a 5.3l, 6l80 and an E38 ECU. I am hoping to learn about performance tuning as well as economy tuning. I am hoping this site can provide a low cost setup for tuning. I am looking into to cloning my ECU for a backup in case of failure. What I am thinking is to have one tuned for performance, one for economy and one stock to be used depending on the situation.
