hello, just about have my turbo install completed and am wondering what numbers to start with in the boondocker box, running it around 4000-7000 feet elevation, its the race gas kit but hoping to get it running right with pump/av and then turn it up to 12psi from there. sled is a 2010 m8,162x2.5 camo extreme with turbo pipe and older style dual injector 2860 kit (think its an 09 kit, any help is much appreciated thanks
