I have the tune and if I keep my foot off the gas ill get around 38 city. With 20% highway going 70
2013 1.4 Turbo mpg

Neither the belly pan nor switching to 93 octane fuel has moved the mpg so much as a 1/10 on a mpg. It is stabilized at 36.1

also think about what an AVG is and how many miles are on your AVG.
if you got a few thousand on the same MPG AVG it won't budge easily...

No, only 800 miles on the odometer so the belly pan and 93 octane if they were going to make a difference would have shown up by now, at least a 1/10th of an mpg. Anyway, it was at 36.1 by 600 miles on the odometer and stable before those two changes and it has not gone up. I agree with the tongue in cheek comment about being glad it didn't go down! I'd hate to think I paid extra for the bellypan and that it hurt the milage. I do believe the reason to install the pan is to protect and help keep clean the bottom of the engine and to potentially improve highway stability. If I noticed anything about noise is that I actually hear the engine a little MORE than before and I don't mind that.

Marty if you want to test your MPG on a new tank of gas, you need to reset the MPG AVG or do the math by hand.
Ummmn, how did you think I was doing this? The math by hand jives with the car's ave mpg indication. It's still 36.1-36.2 after 1000 miles on the factory fill oil. The belly pan and the 93 octane made no difference.
I have just over 1000 miles on the car now and the combined mpg bounces between 36.1 and 36.2 and hand calculates out the same. I make the same rolling to hilly drive daily. The belly pan and 93 octane tanks of fuel have not changed the milage. It was 36mpg by 500 miles and hasn't improved since. This is a completely stock 1.4 turbo 6 speed manual hatchback. I'm very happy with the car and I look forward to some strictly highway runs. Our dealer claims a local guy who makes the 100 mile highway run between Cincinnati and Indianapolis and gets 44mpg highway.

I would say it's the rolling hills that kills you, my regular daily commute is usually 39-40mpg. When I travel south in the valley it's really flat and I get great mileage usually 50-54mpg.

I've gotten a couple tanks that nearly got 50 mpg.
How are you tacking your gas milage Marty?? From your post you are going off dic and also hand calc but what are you basing your # off of. For instance I fuel up. -reset DIC and Trip. -refill when I get close to running out of gas. -fill tank. -calc mpg. Trip/gal=mpg that tank, I do this every tank and log it as well as my DIC mpg.
The reason I ask is it sounds like you are doing a lifetime mpg calc. Almost every subsequent tank I've had has varied by atleast .5 mpg even if I made no modifications and had a near identical drive cyles. I've had as high as 49 and as low as 34mpg with an average of ~38-40 mpg (20%rural- 30%city- 50%highway usually). If you are doing a lifetime avg it will take along time to notice anychange and it will be hard to notice if any change was due to drive cycles, mods, gas, etc.
Don't take this the wrong way, I'm not calling you out or saying your doing it right or wrong . Simply trying to understand your style of doing this because I would expect some mild variances between fill ups mods withstanding.
By thw way I saw no definitive numbers to support that either running 93 or a bellypan were better than the alternatives. My max was about 0.5mpg better on 93 vs 87 with very similar drives, but at 500+ miles on either tank simply idleing a little longer a few times could account for the difference. Same with the belly pan but my comparision for it have the bellypans before and after has been thrown off by mods, so I don't have enough data to paint a picture on it..
