Hi,
Not sure if this has been reported already, I've read the Op and the last couple of pages.
When adding a MID RPM turbo kit to car(s), the graph in setting (green power line / orange torque line) isn't updated, but the specs in the box of the top right corner (where picture of your car is) are updated.
To get the graph to change, you need to reset turbo kits to default and then reselect the turbo kit you just put on your car.
Whereas, if you buy other tuning parts, the graph is immediatetly updated with the new power / torque settings.
I hope this isn't a repost - sincere apologies if it is.
Keep up the great work
H
