Ive had a quick look in ida comparing the tf and tp files, and they quite similar with the tp just having a few extra functions.
Also the tf uses tp 2.0 for flashing, while the seat exeo 1.8t me 7.5 for example still uses kwp 2000.
I bought the tp ecu so just waiting on it to arrive now.
i can confirm TP - TF crossflashable
ive got a chance to run it today
pros:
DSG feels like a factory setup: much smoother but idk about nsyw/tsyw for now due to short trip
able to run air condition / cruise stalk via wires for mk4 platform
cons:
needs lsu4.9 and im still cannot converse it to 4.2 idk if its possible but changing LSU not a problem in case
idk what software to use here for logs
