one mod Im interested in is fog light cavity inserts that deflects airflow, although all told it may not be that much of a difference. The car is quite aerodynamic already. I plan to focus primarily on drivetrain, synthetic fluids, gear ratios, underbody smoothing, and weight reduction. I drive this car 128 miles, 5 days a week, so even small mods are welcome. If anyone has input for this unique car, I'm all ears. I've read through the ecomodding for beginners, 100 tips/65 tips and very few actually APPLY to this car. The design of the engine the forced induction and direct injection make this car a puzzle for most. I have the equipment to do tunes, so that is the first place I am going to look, analyzing everything and seeing where I can shape the fuel map and timing to suit the sweet spot in my daily drive, the 57-67 mph sweet spot I usually drive within 90 percent of the trip is where I want to trim things if I can.

For the person who said 89 octane, this car can accept any 87 or higher fuel you put in it, however, ambient temp and humidity seem to play hell on this car's overall performance and even mileage, where it affects a normal car, it is amplified with the forced induction. I escape this by running 93 octane, the car then utilizes full timing and cam phasing. We don't have 91 octane here, and 89 is actually 90. WIth the price difference being negligible and doing the math, I pay maybe 15 cents more a fill up for my car to behave perfectly when the weather is hot or humid...or both.
