Was that a really new SI board (as in from your dealer), or a used SI board (as in from a salvage yard? If the latter, get a truly new board from your dealer and see what happens.

That said, the speedometer should not be affected by the SI board. That would make me think that there are other problems in the cluster.

it was a used board from rares in arizona....when the board originally fried there was smoke from right over the steering column....i pulled it and it was defintley fried.....

Smoke from the cluster??? There may be more wrong than just the dead SI board. Pull the cluster, disassemble it and check for other damage. Also check the wires that connect to the cluster for damage. Then check the fuses.
