SO after a few weeks of tweaks i have not been able to get the engine to hold a steady rpm with the transbrake feature. I have tried a few setting in the desired airflow table and actully had it working for a few days would hold 3200rpm and 3-4psi of boost. But as weather changed it stopped holding. Now it surges like on a slow limiter, opening and closing the throttle. In fact the converter actually broke today in testing new settings. It made a horrible squealing noise and i now have a converter that will not slip and pulls the idle down.
