Ok, my question how do you custom tune your car to run a set of twins at 8 psi of boost? I new here to the tuning stuff, so do you use a hand tuner or computer program? What is the best program/tuner for my car if I ran twins? I want to dump methanol/H2O at boost levels above 6psi. The fabbing stuff is easy but this tuning stuff you have to find something that will actually do what you want it to. Thanks guys.
