When I bought my truck a few months back it was getting about 13 mpg. I did the Gotts mod, and put an AEM dry filter in. I noticed a little increase in the mileage, to between 14-15 mpg. A couple weeks back I took off the stock exhaust and had a Flowmaster 40 Series (single in/dual out) put on. Today was my first fill-up on the new set-up - 15.8 mpg with the air ON, I'd guess 90% of the time. I also noticed better throttle reponse. Happy as he** - plus I love the sound! I'm guessing maybe $300 for the whole deal - $260 for the exhaust, $40 for the filter, and $20 or so for the Gotts mod. Worth every bit.

An engine is often compared with an air pump in the way of making it perform better; allow more air out, and allow more air in.

Wow, not a bad increase at all. I pretty much have the same setup without the Gotts mod and I get around 13mpg's. I should mention that I recently installed a 2.5" level and 33's with the 5.4, but I really dig the new stance!

Is that the actual mpg? Or is that what the dash says?

I don't have the gotts mod, but I do have a flowmaster exhaust, I have 33" BFG's with 5100's leveled and I get 13-17 mpg with mix of mostly city.

If my indicator needle is accurate I get like 15... Around 280 miles on 3/4 tank. And 24 gallons fills the tank from when the low fuel light comes on

Actual mileage/gallons to fill up.

Explain the gotts mod to me please. And where can I find that filter?

The gotts mod is replacing the piece that goes from the air filter cover into the fender with a piece of pvc
