NA cars are not really easy to tune for extra power. I would save the money.
I drive a 520 pre LCI (btw, the LCI 520 someone saw in SG are 4-pot 2L; I think it is the same engine as the 320i; maybe some tweaks here and there, not sure). I was driving a 1.8T tuned 200bhp/300Nm before I turned to this 520. Initially the "loss" in power was very obvious. But then I don't drive agressive so I got used to it after a while. Now I have forgotten what 200bhp/300Nm felt like.
It's more than enough for daily drive. Overtaking is a breeze with smaller cars, even with Camry 2.4. No problem. Honda 2.4, not sure. 177bhp/210Nm is not exactly lousy ...
