Did you confirm the over-boost switch works by comparing it to what the readin gis on the boost gage when it kicks in?
Are you using the clock VDO boost gage or the POS tach gage to monitor boost levels?
Make sure the wastegate hose to the TIAL unit is securely mounted and not leaking.
The vent to atmosphere for the TIAL unit is not blocked?
Try to check simple things first before changing out parts.
