Problem with speedometer even after SCT 2

[Dr.Jay]

I have a 99 SC GT with 4.10's with a 2001 Cobra cluster (160mph vs GT's 150mph). Naturally, the speedometer is off. The tunner corrected the tire diameter and the gear ratio, but my speedo is still off by like 60mph... he said the problem might be related to the cluster being from a Cobra... what could I do to fix this problem? Thanks in advance guys...

BTW, a SCT Xcalibrator 2 was used...

I wouldn't think they would match up.

But Guys are swapping 03 cobra dashes into fox bodies so I"m sure somebody can do it.
