Ok so I was looking in my summitracing magazine that just came in.. I have always wanted to buy the MSD-6T and rev limiter... but i see a MSD-6AL as msd ignition and built in rev limiter... $236.. not too bad... by the way it is pg 73.... well back under trucks pg... 370 they have MSD off Road ignition and MSD Offroad rev control... $254 + $113 = $367..... why so much more? am I missing something? is the 2 offroad ones better than the 6AL????
