Well I ask because I have a friend that did a tune on his Ford Focus ST and got more power I was just curious if it would work on a NA engine. I'm used to old school engines not these new computerized cars lol
I'm new to newer car upgrades. What I'm wanting to ask is if a naturally aspirated 1.6l Nissan engine can have a tune performed on it. If yes what is the process, cost, and HP increase??
