Yes, obviously a dyno is the most accurate, but my goal was to see if the software was actually installed or not. With a stopwatch in sport+ I did 5-8 runs and they were all 4.9 - 5.1. After the upgrade they were 4.3 - 4.5. I don't care what my rear wheel hp is, I just wanted to make sure it was installed, which I did. Have you confirmed yours?
@ hammadurb My dealership sucks and is also unethical, great combo.
@ huanjf The M Sport has the same hp as the non M, but the long wheel base in most tests is .1 sec slower to 60. So figure 5.1 stock, 4.4 upgraded.
