^Excellent, this will be a really fun build. I read your also working on a MK2 Supra, my buddy is in the process of building a MK3 shooting for 800+hp that he stores/works on at my place. When I get home you will have to come by and we can shoot the shit.
As for tuning I am using the turner S50 chip but it is running lean. I am getting it flashed 5% percent higher so I will let you know how it works out.
