Why don't you try Jenvey or even Steve broughton at SB Developments.
They do everything red top
and Steve actually mapped my TB's set up in my 2.0xe set up
I had the TP208 kit with MBE ecu (nice and small compared to stock)
There is also a firm in Sandbach called Advanced Vehicle Technologies who manufacturer all sorts of stuff for TB's owned by a Mr Mangoletsi
they have an office in knutsford also called Mangoletsi manifolds.
