I was averaging about 34 mpg for the first 5k or so miles on my stock 22 Si. I've been tuned with TSP for about 5 or 6 months now (8K miles total) and my lifetime mpg is now 31 mpg. A lot of short trips and some highway driving in there.im wondering if the TSP and Phearable tunes noticeably impact the fuel economy? Can anyone share their experience with this?
