Initial acceleration hesitation/stumble ps1000
 

Hey, I've got a ps1000 on my 13bt, its got a bad hesitation mainly when cold on initial acceleration from 0% throttle it almost stalls, I noticed in the transient throttle settings it's set to 10% before the enrichment occurs, do I need to lower this heaps down to say 1 or 2%?
Or would it more be related to the load settings in my coolant correction needing more fuel?
