Dod removal, firmed up shift points, engaged PE sooner and worked a little on Torque Management. Had an issue and posted previously about it but I think its squared away. Biggest thing if you take a look is I was curious about the timing. I added quite a bit and was only getting some spark knock in one small area. I feel like I could keep going and then back off once I seen some KR but wanted a some input to make sure I'm on the right path before doing so.. Truck is bone stock minus a CAI I have coming but isnt on currently. My biggest goal is towing, Not racing around so any suggestions would be very appreciated. Thanks and love the board!! Lots of great info.
