Other than that, narrower lrr wheels and tires with max psi an option?

Well you have chosen possibly the worst car in history to get good mileage from! Its tuned to go fast, accelerate like stink & smoke tyres with ease. Cool cars though you can't beat the noise.

Also the TPS probably bears no relation to butterfly opening angles. Its usually not linear & will be tuned for performance.
