The car is coming along nicely, mileage is getting better the car looks good in my opinion.
Soon I will do the Trifecta Tune and I think it will bring everything together for good performance and mileage.
Lately mileage has been down some I think due to Winter blend fuel and colder weather. My city mileage had been up to 26 and it is down around 21 now...... Should be (hopefully) a temporary thing.
I do not think the Apexi fuel controller works with the Chevrolet cars. That does appear to be an interesting addition though to fine tune the fuel ratio.
The Ecotoc only has the air conditioner and alternator running off of the crank so I do not think an underdrive pulley would help this car much if any.
