Hiya Steve,
I do not yet have B.K.P Tele pickups, but find that with Teles in general, I get the best result with the bridge pickup 1/16" level across from top of low and high 'E' polepieces to underside of low and high 'E' strings ( held down at the last fret ).
For the neck, 1/16" again for high 'E' and either level or a touch lower ( at 3/32) for the low E to keep the bass twangy / zingy.
Sorry I could not have been of more direct help .
