Being a gearhead from the old school,and setting up my own timing curves,jetting,etc. How do you know what that chip is REALLY doing? Is there a way to tap in to the computer and get real time,under load,timing readings? Would be nice to actualy see what you have in the stock setup,and see what the chip gives. None of these chip tuners tell you what kind of advance curve you have or are getting. I assume the 4.6 Bullitt engine runs best somewhere around 32-36 degrees total. I just want to know what my engine is running with,not take someone's word for it.
