ok i have an 89 TII and had called BNR turbos to build me a turbo about a month ago and i was telling him that i wanted to run about 15psi but i wanted to upgrade the fuel system.. he told me to get 4 720cc injectors, retard the timing 2 degrees and to tune it with the safc II. is anyone running a set up similar to this if so,, a little input . thanks
