Of course you can re scale. You wont be running 30 psi on the zetec with those pistons (stock?) and that turbo so re scale the whole thing for 1.5 bar to start with. Same with your fuel map.

You are right about the inlet. Chances are you might have to pull a load of fuel out and whack some more advance in. lol

Make sure you log you AFRs prior too and after fitting. Proof is in the pudding and all that. I know the fabricator is a genius tuning god but only the cold hard numbers will prove if he has gone in the right direction or not.

Anyway, i seem to have doubled my last years post count in this thread!
