Strategy questions

[dhanna6powerstroke]

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.

It is certainly possible. Go back and complain until they give you a better strategy, if they can. Unfortunately, they might not be able to go back on strategies without sending the PCM to a repair depot.

The heat inductive strategy was designed to help with cold start issues, mainly to prevent injectors from crapping out! It doesn't affect mileage.

Perhaps it is time for a tune.

I've had tunes. My problem is, I don't want to get a tune to get my mileage back to where it was stock on the original strategy. I know the heat inductive strategy doesn't affect mileage but it kills FICM's. I've never had cold start issues, so I really don't want the heat strategy.

Would this strategy work in my truck?
ECM- VXAP2A2
TCM- TQAU0N4

I would contact PowerHungryPerformance. They have pretty much all the strats from all years. The most knowledge of what works and what doesn't.

This is what they recommend for our 04's:

2004:
VXBC7xx
VXBC9xx
- Replaced with VXBC6xx

Don't bother. They are closed for the week of thanksgiving. Although you could send an e-mail and be nearer the top of the list for the following week! LOL
