Also I forgot to say the fuel maps are completely different between a P14, P13, and P28. And H22a will feel like it pulls hard because the fuel maps are designed for a motor WITHOUT vtec. So it's gonna allow the most amount of air/fuel to produce more torque on the bottom end of the rpm band. We all know H23's have no top end .....(except mine). J/K. But the P28 is designed for a motor with no where near the same amount of torque. So of course the fuel maps are completely different to maximize a vehicle with 1.8L's of displacement. You will only feel the true power of an H22 with a P13 ecu or a chipped/remapped P28 ecu. Anyone please correct me if I'm wrong. I gladly admit to my mistakes and I don't want to pass on incorrect informtion.
