i will try.
if i dont keep it marginal and i am on tool 1 and choose tool 8 it will over shoot tool 8 index and end up in tool 1.
if i choose a closer tool then its fine.
now if i keep it tight and move from tool 1 till tool 2, when it reverses its effectively driving against a dead stop for milliseconds. then when i select tool 3 it dosent quite make it.

What happens if you keep it tight and index from tool 1 to 8?

its fine. but if the reverse stage stalls the motor at all it wont make the next change.

Only reason I can think of is mechanical. Could be that the motor locks the turret so tight that when you command the next tool it loses steps trying to accelerate. Try decreasing the speed and acceleration of the A axis in motor tuning to some real low values ( I would say at least 1/10 of the current values) and see what happens.

It shouldn't. The moves are incremental.
If you want to reset the A axis after a tool change, just add this line to the end of the macro:

Dan you where right, it is mechanical.
i stripped the thing down and what did i discover, alternating ratchet distances. the tool turret holds 4 external tools and 4 internal.
is there any thing i can do.

That's bad news. That macro won't work then. You have to move in absolute then. Consider the macro that Hood suggested you at the beginning.
