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.
I emailed TSP support asking if the 241whp/286tq is the Map 3 (25psi) results and they confirmed it is.
"That's correct the numbers would be for MAP 3 which is for our tune. The MAP 1 & 2 are reserved for the tunes that come with the KTuner itself."
