No, no, your caster level increases up to your HD. Or rather remains the same, because all psionic powers already have a caster level equal to your HD (since they are spell-like abilities and their caster level is not otherwise stated). Remember, manifester level is a property that psionics have in addition to caster level, not instead of it. Even with full transparency in place, they're still separate values.
