Yes it would, we went over in this thread why fitting bigger injectors was a bad idea.
The BA turbo injectors aren't massively large, but it will still be over fuelling.

But anyway try fitting the reg round the other way, like reverse how the fuel lines are hooked up, I'm not 100% but that seems like the wrong way round to me, and you've got nothing too lose hahah

ok ill try that. ill try anything atm. one of the blokes earlier in this thread said that this is the way to do it but ill try the other way because it has to be hooked up wrong or the fpr is stuffed
