It's modest at best:


From OV Tune on my 2017 Mazda 3 GT Auto (2.5)

I crunched some numbers from the raw spreadsheet log, but then confirmed it with the MazdaEdit...specifically looking at the Dyno - Speed and Distance Tab.


Stock :

3000 - 5000 RPM took 6.858 seconds
80 - 120 KPH (50 - 75 MPH) took 5.927 seconds

Final:

3000 - 5000 RPM took 6.715 seconds
80 - 120 KPH (50 - 75 MPH) took 5.787 seconds


Sorry... but trimming 0.15 seconds for $600 has to be the worse investment ever :(
Why would you purchase a OV tune for your stock 2.5 matic ( no mods) and expect the additional 20HP to turn your car into a rocket. OV website was clear on what gains to expect with or without mods. With some research ,,, expected performance gains with mods + OV tune. In your case i would have used the $600 to swap the automatic for a Manual 6 speed.

Maybe you should tell the whole story before you start bashing others....
That was the guy who didn't have a clue how to use the software or do proper data logging, and thought he was going to get big numbers from an 89 octane tune by using 91 octane after the tune was done......so he got out of the tune what he put into it - which was absolutely nothing, and did nothing but complain about it, even though the results were entirely his fault.....
I did a real tune, 93 octane, did proper data logging, and got good results. My car went from about 8 seconds to 7.2 0-60, timed using a scanguage and repeatable, not using the Mazda Edit software, and is far more driveable across the entire RPM range.
Oh, and the other reason why Matt stopped doing Mazdas is because too many idiots expected miracles, right now, didn't do their part during the tuning process, and wanted his full attention all the time. Not worth it for a couple hundred cars when the Toyota market is many times that...

@arathol Would a track app being able to do a 0-60 time reading or even be capable ?
