A MSD box can you ruin your weekend also..We have had so many failures in TAH and when we started in NHRA a can't tell you how many boxes went sent back..got to the point we had replacement setups that could be changed in minutes..Our last trip out with the Eliminator the MSD blue box caused some issues..But thats Dustins deal now..he'll throw in a new box, filter and plugs and be running in no time..I'll sit back and relax and think about racing boat again...
