This next weekend, the car will finally be getting the PI headswap with bullitt intake manifold. I will also be throwing on my mac lts and x pipe. Just wondering about the tune. I have a diablo chip right now and can get it dyno tuned. Should I use the chip with dyno tune, or buy a handheld tuner and do myself. Have to pick between one or the other. Thanks in advance.
