Recently picked up a new (to me) Escalade for a great deal. Needed a torque converter and had a bad lifter. Fixed those with all stock parts, just going to sell it after I fix a few other minor things. I did do the AFM disable, and adjusted the trans shifting and pressures a little. Seems to run good. What else can you do to a stock 6.2 to help it? Enable PE earlier? adjust timing a little? Did some searching, but was having trouble coming up with tuning a stock 6.2. Any help would be greatly appreciated!
