So it is like bootmod3 flashing an engine tune + a GTS tranny tune + throttle response.
Yes that does transform your car but please stop saying they are doing something very unique and special. This is what Ecutec Racerom was doing in 2010 on pre dinosaur engines (EJ257). That is about a decade ago..........even additional features that were not OEM were simply plugged in: flatfoot shifting, rev matching, gear dependent boost, flex fuel sensors, throttle response, I don't know what, but it was a lot!
Then after my 5th wrecked subaru engine I bought an BMW
And I am not a hater !!
(just to be sure
)
