Fuel Economy update before and after straight-pipe & tune.

2012 JSW with Rawteck full straight pipe, and accompanying stage 2 tune. For these calculations I used the odometer and the number of gallons from the pump. I know the MPG in the car is inaccurate... or is it? Before my mods I was getting around 410 miles on 13 gallons of gas. I would average 31.5 mpg. Now after the mods I can do up to 500 miles on a tank. This last tank of diesel I went exactly 470 miles on 13.29 gallons of diesel. Which puts me at 35.36 MPG. Now for the fun part! That 3.86 mpg saved me about $110/10k miles. Assuming diesel is 3.19 which is normal for my area. I definitely plan to put another 100k on my car which will bring my total savings up to $1,100! The whole kit only costed me a $1,800. If you consider the 30k miles I've already put on the car then, by the time she makes it to 250k the kit will have paid for itself! This dosent even factor in all the money I am saving in maintenance over the course of the vehicles life, or the extra savings if diesel hits $4/gallon again. I can not recommend the Rawteck performance exahust enough. I get to spit smoke, go faster, sound better, and save money AT THE SAME TIME!
