I had my truck reprogrammed because of a TSB that I found about putting an 05+ trans in an 03-04 truck. Since then my fuel mile has plummeted. I'm getting around 12-14 now and before I never got worse than 16-17. Here are my before and after strategies. Original strategy, ECM- VXBC9NA, TCM- TQBE0NL
Updated strategy, ECM -VXBC9F2, TCM- TQBF0NB
I wanna know if the updated strategy is the cause of my lower MPG and if so, what is the best strategy to have and how do I get it. Don't care about having heat inductive strategy. Also, truck seems to have less power with new strategy. Thanks for any of input.
