impolaris

Hi! I currently drive a 2013 Chevrolet Impala LS that I bought used recently. I was getting onto the highway this morning to go see a family member and had a lot trouble keeping up in traffic due to a limitation of 70mph. The person I bought it from lived in a very rural area so I'm assuming that they set the limit so they would always be safe, or it was for a teen. I would take it to a tuning shop but I'd rather learn how to do this myself and save some money. If there are any resources on ECU Programming or any other way to change it then please let me know because this limitation can seriously get me hurt.
