First Road Trip, a Couple of Issues

clusters are simple to replace, any tech can handle that, remove the trim around the cluster and it's held in by 4 7mm bolts then uplug the connectors and install the new one. the hardest part is getting the correct program in the cluster aftwards, since it's a programmable module you have to program them when you install a new one.

Sometimes we have run into programing issues and have had to reprogram using the as-built data other than that a cluster is very easy..

the cowl cover is held on by 2 pin type retainers and clips, you only have to lift up the passenger side cowl cover, then lay a bead of clear rtv right at or above the cowl cover seal

In general, you will find that nearly every new car will deliberately over-read compared to actual speed as it has ramifications for speeding offences if it under-read.

You clearly have 2 separate problems.

1)From my understanding you have both the factory wheels and gears on the car. The easiest way to see if it's ford's problem is to return the vehicle to factory tune first and retest.

The Spedometer issue is most likely caused by your X-Cal II. Is it possible that the incorrect revolutions per mile is set in your tire diameter? With all the speed sensors in this car it's virtually impossible to have any inaccuracy more than 1% since everything turns at certain ratios unless it's a software error. If you bring it to ford they'll reflash it and you'll lose your tune.

2)There have been many people with the dreaded wet passenger floor problem. The problem is more than a simple wet carpet. In the passenger kick panel there is a 2nd fuse box called a Smart Junction Box or SJB. In other cases the SJB was getting wet and shorting out causing major problems. That one I'd get done by the dealer for sure.

for the water issue you may have somthing blocking the drain for the a/c evap core. if you look at the firewall under the hood with the car up in the air you should see the drain almost directly under where the a/c lines enter the cabin. B low that out with compressed air.

Another thing that can cause this and is common on many fords is a water leak coming from the passenger side cowl seal, this is easily solved by removing the cowl cover on the passenger side and running a line of RTV under it and reinstalling the cowl.

As far as the speedo is concerned we will not attempt a repair on that, it's considered normal on any car for the speedo to be off a few mph at highway speeds.
