Trying to try to see if I go away from the computer if it'll solve my problem, been fighting it for years, after fire issue on Decel, I have tried everything and the only thing that has stopped it is if I disc the four wire pin at the Dist, car has no power but will not pop on decel either.

Do you think the Double Pumper would be too much for my application? I am guessing a 650 or would you go with a 750?
