just out of curiousity how can you say the box adds power when its sole job is to retard timing under extreme cylinder pressures(i.e detonation)other than the fact if you dont have detonation you can safely accelerate without internal damage worries,but to say it actually increases power is false,and also not a gaurantee that you will get rid of all detonation even at its greatest adjustmant which is equiv. to 10 degrees timing retard,i have three supercharged Vipers here 2 heavily modified,one no detonation at all no MSD box,another even more modified,some detonation,3rd bone stock other than S.C and tubes, still some heavy load detonation W/MSD box adj. to max,so we dont want to give anyone a false sense of security when it comes to detonation,please listen carefully for it and remember just because you have that box does not mean you cant have detonation,the only gauranteed cure is a fuel management system,and do not expect to be gaining power by turning that retard knob to the right ,YOU WONT!
