More power comes from fuel and spark, where you can go with these I am still learning. Compression increase is a huge power adder on a 460, 9.2 - 9.5:1 and it can still use regular fuel.

I purchased a Mongoose pass through cable, BE2012 and the AGANN strategy form Core Tuning. I also had to buy an EEC-V box so I had one to use. Adam Marrer at POPS Racing is a good resource and I'm sure will be happy to set you up a good tune for a price (that's his business). I don't know what your emission laws are, but my truck is an 86 model and as such was built non-catalyst from the factory. I have a pretty free flowing exhaust on mine.

You do have the better EFI heads on yours, right now I have E7 heads, yours are the F3 heads. There are some RV cams available (RV because they are for heavy vehicles or towing), the MAF is more tolerant of a hotter cam than the SD systems. If you start a new thread, link it here so I can follow it.

 

I need some advice guys!!

I have a 2002 F250 Super Duty XLT Ext Cab, with the Gasoline 5.4L. I was wondering which programmer chip everyone thinks would be the best to purchase/install in my truck for better Fuel Economy? If anyone can give me some info/advice I would GREATLY Appreciate it. I was wondering if I should maybe install something like a Cold Air Intake on her too if it would help me out some as well. Right now my MPG's are 8/City and 12/Hwy. I'm hoping maybe I can get it to 10-12?City and 15-17/Hwy because my Father has a 2002 E250 4x4 Van that is getting about that MPG's. (Which if I might add, his Van is AWESOME). Below is all the info about my truck..

2002 F250 Ext Cab

I'd appreciate it GREATLY though if anyone can help and give me some advice on which route I should go to see a little change in MPG's without messing with my Gear Ratios!! Thanks guys!!
