The main reason why you want to go with a custom tune is that it is married to your vehicle. You data log it, and can see how your vehicle is reacting to the tune and also to see if any changes need to be made. You can't do that with super chips, the sct canned tunes are probably no better than the super chips. It is just better to run custom tunes that are married to your strategy code. There are 5 major brands out. SSI, MPT, 5star, Unleashed, and Livernois. Livernois uses the mycal device. I recommend sticking with the sct device. Can't go wrong with any of those. All good
