#152716 you will want to get it tuned after the swap. I think you will throw a code otherwise. It also wont run that great either.

#152751 You will throw a code for the inlet air bypass (IAB) system if you don't have a chipped ECU with a CEL eliminator. You'll also see a decent increase in power, not a huge amount, but you'll like it. That IM on the B18C1 was not the greatest design in the world, IMO.

As far as fuel flow, just keep an eye on fuel pressure. Make sure it doesn't dip below what it is at wide open throttle on the factory set up.

Tuning will help you out with all of that.
