So 2017 oct vrs (remapped), I had the boost actuator fail, conveniently the water pump failed as well. Any ways had them both replaced at a local independent garage.

And now it's like the remap has been removed or there's a huge boost issue ...the new turbo is an IHI TURBO model number is 28084-00 does anyone have any clues on what could have happened 

Check for codes. Log boost actual against boost specified. Ask garage if they can think of anything. Wastegate actuator maybe not set up properly but would show in the two suggestions in opening of this response. 

It's going back in on the 30th for a smoke test in case there's a boost leak and they'll look it over they are also going to talk to the company who mapped it to see if they can think of anything as they said they've rad revo mapped cars where the maps turned off when the battery has been disconnected for too long
