Hi.
Welcome along.
Sounds like a great buy. Photos please

I've no idea what the wax block is
- intrigued.....
Not sure about EGR bypass with boost sensor. I can't see why it wouldn't be OK but I'm sure someone will be along soon with the correct answer.
AFAIK there's no-one in the Midlands who does a 160 remap. Contact marinabrian or Phil T4 as I'm pretty sure they can do a postal service. Or take a trip up the M6 to Manchester to see Civil Steve and have her remapped on his rolling road. Good guys, all of them.
Good luck.
Andy.
