first off is the power stated as 'at flywheel' or 'at wheels' ?
as others have stated 191bhp for flywheel figure is low but ok for a @wheels figure.
so your car seems close or at good health for the std map...
with the remap the differential in std vs mapped seems very low. I would expect +40 bhp and +40 lbs/ft (roughly)
interestingly your bhp increase is very low but your torque is up by more which may indicate a boost issue.
(as others have said a torn diverter valve, boost leak etc)
It may also be, that following remapping the increased pressure has finally killed your DiverterValve which was just about coping on std boost levels
Tricky to change on a K03 car but the part itself is cheap enough (£45)
are you manual or DSG ?
Can you post pictures of the two plots up for us to see?
Which map is it? [edit : I see this is in the GAIC section
]
I assume you use high octane fuel too.
You need to get someone to check the car for fault codes using VCDS
(see if any members on here are local to you and are willing to help) to check the overal health of your car
like others have said its a fair bet your DV has just given up
, quite common.
let us know how you get on
