So I have a 2002 mustang gt. Recently I blew a spark plug out of the head (typical) I decided to tear down the whole engine and build it. Im going to be doing a single turbo set up and my biggest question right now is could I be able to adjust power levels from say 450 up to 600 with a push of a button on a tuner. Is an electronic boost controller the best way to do this? And do I need 2 separate tunes on my x4 or whatever I use so when I turn the boost up I change the tune from ”daily” to “race” etc? Also I have 18cc dished pistons giving me about 9:5:1 compression I believe, is this a good CR for boost and how much boost can I run and still use pump 93 octane? Any advice is appreciated this is my first turbo build and Im looking forward to it but Im kind of in the dark on the whole tuning and adjustable of it.
