I did a ecu reset by removing the negative battery cable and pressing the brakes and it seemed like the brakes didnt even come on i couldnt really tell tho since i was in the car. But all my radio presets were gone when i started. When driving it felt the same to me, maybe because i usually rev to like 4k?

 

a reset isn't really supposed to make ur car faster. it just basically clears out the computers mind and starts all over. you should do it usually after the break-in period. i did it and i felt a big gain while taking off fast. not really a different after 4-5k for me. usually people also do it after they install some mods and then get their ecu reset by technosquare. yes, my radio presets were all gone also after i did it so it did work for u.
