Went to datalog a few pulls on the GT for another forum, and discovered a few interesting problems:
-When the program is online and reading the data, manifold pressure is read in psi. However, when looking over the recorded data, the manifold pressure is not only in kPa, it's now negative... did not touch any settings (nor can I seem to find a conversion setting)... wtf?
-On a fourth gear pull, at around 5k the tach needle started jumping around violently under boost (around 1bar). Datalog shows relatively even manifold pressure, WOT, and also logged the RPM bouncing. The weird thing is, I didn't let off right away (having had this problem in lower gears, I wanted to get a good log of it) and while the engine speed was supposedly bouncing around, the car was still accelerating hard, certainly harder than it would if it had hit a ~5200rpm limiter like the log is showing.
Any ideas?
