2008 cobalt lnf tuning question
Hi I have a 2008 cobalt ss turbo and im looking to buy hptuners and get a remote tune. The possible problem I may run into is the fact that the car previously had a trifecta tune on it but I am unsure of what happened to the tune (and I verified it with trifecta themselves but they were unable to give much info) . Currently the car shows no signs of having the tune installed. ( I have tried everyone of their activation methods multiple times ). My question is at what point will I know that the PCM is tunable and not locked and will allow me to log, download, upload and get a remote tune from someone. Thanks for any help
