my current xr6t has no real engine mods to it other than a hyrbrid intercooler kit, k&n filter and F6 cai. I would like to get it tuned, but I dont know any places or what is a safe psi to run, im looking at about 12psi. Is 12psi to much to run on a stock engine? and any places around the newcastle, nsw area that could tune it or would I have to go to sydney? thanks.
