I have bought a mustang coupe with a brand new 7al3 already included wondering is this a good ignition to use with a BBC nitrous motor having 2 systems a plate and a fogger or is it worth it to spend the 900 or with on the digital 7 in which I can control the nitrous systems and tune them better just the give and take and do you think it's worth it to go with the digital 7 with my setup..thanks in advance
