Hi guys. I'm using e-manage for my car. Last week i've tuned my car. Let say i want to change my gain(boost response) and peak gain(stabilizing boost) setting, do i need to retune my car?
I have been using ron 95 for about 5 to 6 tanks. Recently i have got a burned engine valve. I am not sure whether it's due to the ron95 or not. i have using my turbo engine 3sgte 245 for about a year...
