Youd have a really damn good butt speedometer if you can "feel" that small difference accurately, since the scale looks to be only off by 12.5%

that would roughly equal 65mph to show as 70mph on the new cluster, depending on how the gauge and pcm interact with each other

yeah i can do that but in my stock housing, i have lights that are burnt out. so i wont want to put the cluster in the old housing.

and for the part number, i will look and have one for you later on when i tear it apart again.

it depends on where the speed is calculated.. the speed may be calculated in the IPC or it might be calculated in the PCM... i do not know for sure... you should test it since we dont know..

look above..

best way would be to plug a scantool in and watch the scantool and watch the speedo at the same time

use a GPS ..... and if you fond that you can make the whole GXP cluster work i can have the miles reprogrammed. If you end up not using it i'll take it off your hands
