I assume it will void warranties so I am holding off of doing pro tunes but am wondering what the average pro tune costs? I hear even at stock a pro tune can give great gains and such. I am having the SPT CBE installed within the week and doubt the dealer would tune for it though i've heard its more or less plug and play.
I'm in MD where i hear Agile Auto is the way to go for tuning. I'm also near Mach V so either is an option.
