I was wondering how easy it is to deal with RAC after you put on a tbe and tune the car?

I'm about to do it to mine, and wondering if they will ask me to have it professionally assessed after this or not....I'll will have to disclose the new HP rating and that it's been fitted with tbe.

Just wondering if anyone has done this with RAC in the past and if just the phone call stating the new HP rating plus tbe was enough or had to go get it assessed.

Just stock car getting tbe plus tune.
