Hi,
PRB ecu, k24a3, turbo Garrett GT2860rs with 10psi, PRB stock oem wideband lambda.

2 questions:
*I noticed that on dyno it wont show richer then 11.4, Even when the real value is done to 9´s. it only show a straight line 11.4-11.5. Tried 2 used lambdas in good condiotion and then bought a new sensor but exactly the same problem.

*when choosing "WOT compensation from WOT compensation tables" it goes to 12.5-13.0.even when I have changed the 9 & 10 coloms to 11.6. And I also noticed that the tables dont have any colums in high pressure/boost.
