So I got some information to share for all the fuel economy guys!
I've been doing my best to keep track of my fuel records since I bought my van 10 months ago. Records so far include the date, miles, gallons and mpg for each fill up. I haven't cross references them with my mods yet but you can see they are pretty steady and consistent regardless of mods which is why I'm a bit perplexed/annoyed. I know some of the mods I've done have had negative impacts on fuel consumption but I was hoping that I was making enough gains to not only offset those losses but still see an increase in mpg's.
Here are all my records since I bought the van concerning fuel consuption:
So far the mods I've done to improve mpg's are...
1) Downpipe
2) EGR Delete
3) Economy tune (100 + hp)
4) Muffler and kitty Delete
5) Lighter wheels and tires
6) Replaced all filters (Both Fuel, oil, and air filters)
7) Run Standadyne with every tank of gas
8) Swapped to smaller antenna (Minimal but I thought I'd add it anyways!
: )
Mods that hamper better mpg's are...
1) Weight of Interior improvements (Bed, shelves, insulation/walls, tools)
2) Weight of front and rear bumpers (400 lbs)
3) More aggressive tread pattern
I think that's all the mods I've done unless I'm missing something. There are a couple more things I can do such as a Kennedy lift pump and make a custom intake but after that I think I'm all out of fuel economy mods unless I really start messing with Aero and stance.
