maybe you didn't understand it is a custom fabbed setup i hae no worries about the turbo kit all being installed and fabbed up thats not the hard part any good turbo specialists can do that, its just the tuning i am concerned with since there is no real software for our cars, he says he would use some mercedes software but i just don't want to bethe guinny pig ya know, i do have faith in this guy he does alot of high end cars and i have seen his work i just really don't want to be first, if there was a tuning software already developed i would have already had this done. i have met with him a few times gone over everything i just backed out at last minute. i think i will wait for something designed to tune our cars to come out.
