FORD FOCUS FUELLING PROBLEM? DPF REMOVED

[motorsportsz]

Hi there
i have a customers 2006 ford focus 1.6tdci 110bhp model.
Customer had removed and gave it in to me for the delete & remap.

At times the car would smoke in first and second gear. smokes pretty bad. black smoke.

The car would also cut off at times and won't start back up for a while.
whilst cut off the car gives the following diagnostic codes.
P1927 & P193, both fuel additive codes.

I have attached the file of the tuning and dpf delete.

what could be the problem? I'm assuming its a leaking injector or fuel pump issue. however, i have been told the cars dpf fluid sensor has to be disconnected from the dpf fluid? I can't see no sensors, only a pipe.

Cheers
