How did your MPG turn out?
You can't fix stupid but, you can adjust it with a 2x4.

My last tank was 24.1 mpg.  Usually hit around 23 mpg before the upgrade.

Can't say the 24.1 was easy driving.  Traffic permitting, I've been taking first to 4500 RPM and 2nd to 5000-ish RPM.  Then quickly getting to the highest, usable gear.

Driving has just been more fun. 8)

My mileage has held steady at 21 in the city. The problem is similar to Pgackerman's that the increased responsiveness leads to a much heavier foot and my face hurts from smiling.  :)
The real test will be after my tune is complete and I enable "lean cruise", or "highway mode" and see what fuel savings are had then. I've only got 4 short gears, so I'm not expecting much.

Car is running great. The idle is smoothed out and throttle response is better all around. I will be driving it to the cruise in tomorrow. I will let you know there what it is like to drive distance and what milage it gives back.

Have you scanned it yet?
If you'd like, I'll bring my scan tool, and we can look at the fueling/BLM.
Provided I can figure out what to scan it as.
(Do you know the "8th digit" engine code of the mask that was used? Ron S. may know.)

29.84 mpg, but I filled up yesterday.

BTW, we had NO highway driving on the way to Sonic.  55 MPH roads and small towns in South Carolina and Georgia.
