Adding this for the next guy...

base tank, only one :-( Will fill up sunday and repeat a weeks worth of commute miles, Mon-Fri nite. Sorry, no ABA test, too many things going on. During my research on throttle response & aluminum DS's I did not find anything with this much detail so... here it is.

513.8 miles, 23.539 gal, 21.827 mpg
100% eco driving, IATs up in the 90's, IAT comp table corrected but timing not dialed back in.

479.3 miles, 21.095 gal, 22.721 mpg 100% eco driving, IATs up into the 100's. No tune changes. Tune needs to be adjusted, smoky after DS install.

DGAS tank 7/30/2018
319.1 miles, 16.172 gal, 19.731 mpg... Tuning tank, lots of downloads, experiments and hard throttle time. Tweeked rail maps slightly, main timing, cut duration by 2% and started working on Post timing. Advanced Post 0.25* in an effort to get the turbo spooled better, reduced the MM3 for Post and expanded its coverage up into the 2000-2200 rpm cells. Worked really well, ultimately I reduced fueling, advanced timing and gained more power out of it by reducing the delay from the Main event to Post event.

8/3/2018
472.8 miles, 21.056 gal, 22.454 mpg...

8/10/2018
454.5 miles, 20.153 gal, 22.552 mpg..
