Looks like a wastegate problem on the turbo, has it been checked to see if it is working?

P0246 Turbocharger Wastegate Solenoid A High
EDC15C2 Turbo pressure. Turbo pressure measured too low.
Delphi DV6, DW10B - Turbo pressure solenoid valve control. short circuit to positive or value too high.

HI

Have you carefully checked all hoses for any signs of splits or cracks?

johnb1 said he did a decat (removed the CAT or smashed the internals out), so now there is no blocked CAT in the exhaust system but technically it's not road legal any more
