[s-cars] Going insane... UrS4 falling on it's face at WOT

Do have a Stromung although mine appears to be intact at the welds.

Did a smoke test to check for leaks today and didn't note anything.  Next we
looked into the altitude sensor.  It should have Ground, 5V and a 0 pin
under normal circumstances.  Mine has 5V at the ground, 5V at the middle pin
and 0.  So that points to bad altitude sensor or ECU.... and since I'm not
just losing boost it almost has me thinking ECU.  :-(

The car also seems to run OK (aside from not having more than 15psi boost
without bucking) until the car gets driven for a while.  Once the car is
warmed up and has been driving a while the severe cut outs begin.  On my
trek home last night I stopped twice to let the car cool a bit before
pushing on towards home.  Each time the car would run better after a little
"rest and cool" period - although the car temp was definitely not hot.

Going to try to swap altitude sensors tomorrow with one from my father's
UrS4.  Would be great if that is all it was even though it is still north of
$200 to replace.
