I wouldn't say its a weak point, but its a definite hurdle. I'm not a believer in the swap to the A9L EEC as I think its WAY too much money to spend to end up with a still stock EEC. As for whether or not the EEC is the cultprit behind the missing HP found in our cars is debatable, some say its the intake setup, some the EEC... I don't know for sure. I say if you are going to spend the moeny to get an A9L conversion and then chip it, you'd be better off (and it'd probably be cheaper) to go to a complete stand alone setup.
