aic is actually a great way to turbocharge na cars or add the needed fuel to turbocharge cars. Yes, you can buy a vpc for $500 or map ecu and new injectors for $350, or you can buy aic for $300 + 2 720 injectors for $150 and do the same thing.
On na cars, the car drives exactly like an na, but when there is boost, the aic will add the needed fuel. It fixes a lot of the drivability problems that happens when you turbocharge an na with big injectors.
