is anyone familiar with SCT flash programmers?

I've recently purchased a 2003 F 150 XLT SuperCab that has Flowmaster exhaust in cold air intake it also has an SCT flash programmer with it and I'm curious to know the best program to get the best fuel economy.

Re: is anyone familiar with SCT flash programmers?

I have an SCT for my Durango, and had one on my old truck as well as it was more heavily modified.

I've had SCT on my Durango R/T for three years with good success. You're naive if you think any performance add ons will increase mileage. I had a horrible engine knock when towing 3 tons, and my only recourse was to get a tune. As there are no AWD dyno's within a 10 hour (one way) drive I opted to go the cheaper route with Superchips first. Superchips failed on all octane levels as I still had engine knock. SCT also gave me engine knock on 89 and 91 octane settings but none on 87 octane, hence why I still use it.

My mileage has remained the same throughout the course of owing my SCT. I did two runs to Florida. One using 87 and the other trip using 91 octane and I did my best to use Shell fuel throughout the course of the trips to remain consistent. Both trips I averaged 15.9mpg for about 2450miles per trip taking similar routes. Running the 87 produces no knock when towing (91 octane produced no knock outside of towing and did up the performance level slightly). The 5.9L V8 has no knock sensors by the way. I kept it at 87 octane since as I tow regularly and would rather get more life out of my engine then a ever so slight performance benefit while using lower cost fuel. It's a win win win for me.

An SCT can be calibrated to your engines modifications and depending on the model you purchase, you can get unlimited tunes. When you upgrade parts you can send in the specs and the SCT rep will send you an updated tune at a specified octane.

If you want fuel economy, don't get a programmer. Make sure the tires are filled with air to their max, and run synthetic fluids all around as that is the best bang for the buck mileage you can truly get. If you want performance over mileage, then by all means, let the modding begin! :)
