Hit the track last night and was really disappointed bone stock ETs in the XKR. It has to be the TCU. To dyno the cat you have to pull fuse 2 and 40 so obviously something in one of those systems is holding back real world power in lower gears.

So this looks like an issue with the F-Types as well as the XKR. Can we just get a DSG tranny jag?

 

2.16 60' - what happened??

More concerning is the 117.2 trap speed after being "tuned". Regardless, yes, I think we can all agree now that there's definitely something in the TCU holding these cars back.

 

I'm also tuned. Car feels fast although I didn't take it to the track. I'm due for a service. How do I make sure they don't update my computer software so they don't erase the tune.
