It's hard to say because I don't know who distributes it over there in the UK. I'd take Crome over Uberdata anyday, but Hondata is still the #1 choice in my book. As far as it fitting, I don't know what you mean. They're all reflashes, you send your stock ECU in and they reflash it with their program, then plug and play.

And no, I would not run your car with standard mapping under forced induction. That's a disaster waiting to happen.
