The lack of volume in the e and b strings is no doubt from the distance between the magnetic field of the pickup and the string... This will move the string into the "sweet spot" of the magnetic field allowing the string to vibrate in and out of the field... propelling the vibration thus increasing sustain. You do this by moving the PICKUP up and down... not the strings themselves... by raising the treble side of the pickup you will not change the playablity of the guitar (action, intonation, etc...) you will simply increase the volume and clarity of the b and e strings... you may notice a slight change in the volume of the g string as well... but its for the better... in a good strat setup the bass side of the pickup should always be farther away from the strings than the treble side.... so just adjust the height of the treble side of your pickups until you get the desired volume... and don't worry about killing sustain... if anything it will increase it... UNLESS of course you lack common sense and put the pickup really close to the string... then it will kill it. haha. good luck.
