Thanks,

At the time, I had the EVO Intake and IPD plenum. I've since added an AWE-Tuning cat-back exhaust. I must say that when I added the exhaust, mileage seemed to dip a little.

The info center displayed 29.8 mpg, which I consider to be quite good. Everything worked fine and extra power in the upper revs was a hoot,

How do I install the ECU upgrade? does anyone have step-by-step?

If you purchased it, there should be instructions that came with it.

Did you get the OBD II cable that plugs into the USB port in your PC? Do a search for Softronic and you should come up with the step by step guide to run the software and read/install the ECU flash.

Make sure to disable all firewall/antivirus and that you are connected to the internet while doing so.

I'm not driving super aggressively - typically shifting around 4,500 rpm.

Over the weekend I took another 300 mi trip, filled up and reset the mpg and avg speed calculator before leaving and ended with 24.7mpg and about a quarter of my tank left. During a few passes I would downshift and get the car north of 90, but for the most part was steady around 75mph in 6th. I've got about 1650 miles on the CS and am usually shifting around 4,000 during the break in period, I expect my mpg to dip once I hit 2,000 miles and start using the upper range of rpms. Once I get the Softronic flash installed I'm hoping to get ~27mpg on trips like these.

Also In normal driving conditions (daily commute in light traffic) I'm about 50-50 on the highway/surface streets and get 18-20mpg. I'd wager that if you take a long road trip 200mi+ you'd get higher mpg. From what I've seen there isn't much middle ground in the mpg, I'm either around 25 or below 20.
