RPM fluctuation and surging

After a fun 300km ride I have little progress, the surging is still there. It’s really notable when the cruise control is activated, I have gone through all the cruise control settings with the Mc cruise people but so far no improvement.
I can’t be 100% confident the new TPS is 100% new as it was in a box with a number of TPS at the Triumph shop, not in a Triumph plastic bag. No error codes showing in Tune ECU.
 
I am pleased to finally report that after pulling every Mccruise wiring connection apart, cleaning with electrical cleaner, giving the connection a blow out with a air hose, inspecting, then making sure every connector was put together correctly the surging issue has been resolved and the cruise control is operating correctly. I have no idea what fixed the problem but I am pleased it’s finally fixed.
I have to say thank you to the Mccruise people for working with me whenever I called them.
