The Kerma tuner arrived on Tue and I sent the stock file and got the tuned file back the same day. Yesterday I went out to do a test run before the tune and another after to have some sort of comparison and I was left with a big grin on my face.
Disclaimer: I used the native app from my OBDLink MX bluetooth adapter to take the two runs. The conditions between the runs were identical, meaning no temp change or other environmental condition that could impact the result, however the road I tested on is not 100% flat but for both runs I used the same stretch of road. The times therefore will not be real representations of a track based run, but offer at least a comparison. Also I did not use any launch control techniques and simply let the brake go and stomped on the accelerator until I reached a point on the road where I had to slow down again.
First run, stock:
Second run, Kerma tune Stage 1:
Now the next question, can I manage to actually get better gas mileage out of it. I'll have to resist the urges to stomp on it, but we will see.
