good tuning on a megasquirt ecu will yield similar results..... to those just reading this post and not completely understanding would say "hey, 310hp and 30mpg... that's incredible".... but you're not exactly showing the whole truth
turbocharged cars are great for making peak power..... but at cruising speeds there isn't a large amount of boost.... in a well tuned map, cruising (ie non wot parts of the map) will be tended to as well, trying to get close to the afr required.... meaning, if you're going 60mph with no boost, then the section of the map the motor is in should be tuned for both ignition and fuel.. yielding higher mpg... there's no reason a 300+whp car on MS couldn't yield the same mpg results
we have ever-changing temps here in washington state as well.... it can be 85* one day and the following in the 40*s and raining.... my old mr2 showed the same mpg regardless (not that I watched it extently... but driving it a lot you tend to learn what sort of mileage you're getting)
