well, I thought that if I put the full light one in the front, and the full heavy one in the rear, then if under full throttle the front of the car lifts, then I'll know the front one is correct, and if the rear of the car lifts, then I'll know the rear one is correct. Right? if the front is running correct, that should give the front cylinders power right away, so that will lift the front end, as that is where the power is coming from, and if the rear one is correct, the rear of the car will lift, as all the power is coming from the rear cylinders.

Should be a simple test, no?
