Very odd. My car throttle feels significantly better tuned vs stock, along with overall powerband.
My tuner switched me over to a euro ROM when I tuned with ecutek. Cannot comment on the exact differences between USDM and EURO ROMs as I don't have the technical know-how. Dumbed down answer I was given is that it's less buggy.
Maybe somebody can shed more light on the difference. @
