Thank you @Dave! My plans/mods for now are just visuals, safety and engine health. I won't do more engine mods for now, never did dyno but i guess it has 190/200hp.
I easily cut 5ºgear around 260kmh(160mpg) but of course isn´t real speed! This has all been with last owner ECU map, wasn't nothing agressive at all (I was surprised), i switched for a similar oem b18c4 map to run some test (gsr i guess), it lost power like i expected. With time and rigth tools i will do a nice costume map!
