Here are the results for a EVOX MR we did in Toronto Ontario. We used a virtual dyno, same road same weather conditions and same starting point for every pull. I know its not the most accurate way to test but it will show gains and losses. To be upfront some settings we did loose power but it goes to show you that adjusting the spark can make a difference. We did about 20 tests and here are the results.
The most impressive part is how smooth the car was.
