this is my first turbo car and i read alot about you guys turning up and down the boost. i know in my supercharged truck, everytime i want to change the boost i HAVE to get it retuned, is it not the same for supras? can i just throw in some racegas and turn the boost up without having to get it tuned with some sort of piggyback fuel controller or what? i guess what i am asking is what do you guys do when you turn the boost up to compensate for the extra air being put into the motor? i want to turn my boost up and need to know what else i need to do with increasing boost.
