RPM drops the instant VSS is detected

[ttls1]

Hi, I have an issue with my car stumbling as soon as I start to move and it appears to be triggered by vehicle speed. I did a test by sitting on a hill with it idling in gear and holding it with the handbrake to eliminate brake vacuum. The instant the VSS went above 0 the TB dropped from 16% back to 11% and the engine nearly stalled. I did nothing but released the handbrake. Could this only be caused by the throttle cracker or could it be a number of things? any help would be greatly appreciated. I have attached a short log and my tune.

Try this, couple of small changes. Might help.
