Wotbox Issue

Hi guys I installed my wot box and I followed all the steps in nishans video, did the verification steps he listed. I am currently having an issue when I shift from 3rd to 4th and I’m trying to do a no lift shift, the gear doesn’t catch quickly at all. Kind of feels like the clutch is slipping, or maybe the wot box isn’t returning spark quick enough? Also happens on other gears. Someone else said to me it may happen because the shift time is to long? When i put the auto button on no lift shift it does work as it should but no backfires/flames or anything.

CST4 setup with stock injection.

 

Try to rule out the clutch slipping while driving without work shifting
