To be fair, very few people actually ever restrict their bikes to 33bhp when they've passed their A2. Remember, you dont have to buy the kit from FI International and there is NO legal requirement to have the restriction documented or certified by ANYONE. The only people that may ask for proof is either your insurance company, and the rozzers if you're forced to prove its power on a dyno if your caught doing silly speeds that a 33bhp bke can't produce, at which point it will probably be the least of your worries
Congrats on the pass though, I jumped straight on a 2004 Bandit 600 when I passed, used it to commute 52 miles a day in all weathers, never missed a beat except the odd morning of carb-icing in the cold days
